Some books are dark because the hero is dangerous.
Others are dark because the entire story feels like a descent into something forbidden.
That Sik Luv by Jescie Hall does both.
Aero is obsessive, violent, blasphemous, possessive, and completely uninterested in behaving like a traditional romance hero. The book combines stalker romance, religious trauma, psychological manipulation, masked danger, extreme spice, and a relationship that constantly crosses the line between seduction and destruction.
It is not simply a love story with a few dark scenes added.
The darkness is the story.
That combination is difficult to duplicate. Some books capture Aero’s obsessive devotion. Others explore corrupt religious institutions, repressed desire, cult control, violent antiheroes, or the intoxicating feeling of being hunted by someone who has already decided you belong to him.
The books below were chosen because they capture at least one of the qualities that make That Sik Luv so addictive:
- Religious hypocrisy and spiritual rebellion
- Obsessive or psychologically unstable heroes
- Stalking, surveillance, or relentless pursuit
- Blasphemous and forbidden sexual tension
- Captivity, coercion, or dangerous power imbalances
- Heroes who are not secretly safe or conventionally redeemable
- High spice paired with genuinely disturbing subject matter
Reader discussions about That Sik Luv frequently emphasize Aero’s psychotic obsession, possessiveness, stalking, chase scenes, dubcon or noncon elements, and the moments when the heroine is genuinely frightened of him.
These recommendations are therefore not “slightly edgy” romances.
Many are extremely dark. Check the author’s complete content warnings before reading, because the warnings below are only a general guide and may not cover every potentially upsetting scene.

1. Honeysuckles by January Rayne
Why readers love it
Honeysuckles is an excellent place to start when the part of That Sik Luv you loved most was the feeling that the hero’s obsession is no longer entirely human.
This is a dark paranormal romance with monstrous desire, intense possession, and a hero whose fixation feels instinctive rather than reasonable. The atmosphere is strange, seductive, and unsettling, giving readers the sense that the heroine has attracted something she may not be able to escape.
It does not replicate Aero’s religious warfare exactly, but it captures his feral intensity. The hero does not merely fall in love. He locks onto the heroine as if she has become a biological necessity.
Romance.io categorizes the book as dark romance and connects it with possessive-hero and monster-romance elements.
Spice level: 5/5
Darkness level: 4.5/5
Trigger warnings: Stalking, graphic violence, blood, possessive behavior, supernatural danger, kidnapping or captivity themes, explicit sexual content.
Best for readers who liked: Aero’s feral devotion, predator energy, extreme possessiveness, and the feeling that the heroine has been claimed by something dangerous.
2. The Maiden by Celia Aaron
Why readers love it
For readers fascinated by the religious corruption in That Sik Luv, The Maiden may be the strongest thematic match on this list.
Delilah enters a secretive religious organization called the Cloister while investigating the death of her sister. Inside, women are controlled, abused, and assigned to powerful men under the disguise of spiritual obedience.
Her assigned protector, Adam, is the son of the organization’s Prophet. He has been raised inside the institution, shaped by its teachings, and expected to participate in its cruelty.
The result is a dark cult romance filled with secrecy, control, violence, forbidden attraction, and the terrifying realization that evil can present itself as righteousness. The book begins a trilogy and does not function as a complete standalone.
Spice level: 4/5
Darkness level: 5/5
Trigger warnings: Religious cult abuse, sexual assault, exploitation, misogyny, captivity, trafficking themes, violence, death, psychological manipulation.
Best for readers who liked: The religious trauma, institutional corruption, blasphemous tension, and exposure of hypocrisy in That Sik Luv.
3. The Anti-Hero by Sara Cate
Why readers love it
The Anti-Hero is not as brutally dark as That Sik Luv, but it is one of the best choices for readers drawn to sexual rebellion against religious hypocrisy.
Adam Goode is the eldest son of a famous preacher. He has spent his life maintaining a spotless reputation and preparing to inherit his father’s ministry. That identity begins to collapse when he discovers his father’s connection to a kink club and realizes that the righteous image he has worshipped is built on lies.
Adam’s response is not quiet reflection.
He embraces scandal, desire, anger, and the parts of himself he has spent years repressing.
The story explores religious disillusionment, public morality versus private behavior, family control, and the explosive liberation that follows years of forced purity.
Spice level: 5/5
Darkness level: 3/5
Trigger warnings: Religious trauma, parental manipulation, public humiliation, emotional abuse, sexual shame, family conflict, explicit BDSM and kink.
Best for readers who liked: The religious commentary and sexual defiance in That Sik Luv but want a more emotional, consensual, and less violent romance.
4. Penance by Lillith Abendroth
Why readers love it
Sometimes the most frightening hero is not the one raging openly.
It is the one who watches, waits, and believes every terrible thing he does has a purpose.
Penance is a dark stalker romance built around obsession, punishment, possession, and the idea that desire can become its own twisted form of judgment. The title alone tells you what kind of emotional territory this book occupies: sin, consequence, suffering, and a hero whose attention does not feel flattering so much as inescapable.
This is one of the more direct recommendations for readers seeking the stalker-romance side of That Sik Luv. Romance.io identifies it specifically as a dark stalker romance and links it with similar obsessive relationship dynamics.
Spice level: 4.5/5
Darkness level: 4.5/5
Trigger warnings: Stalking, surveillance, threats, violence, coercive behavior, psychological manipulation, trauma, explicit sexual content.
Best for readers who liked: Being watched, dangerous punishment, obsessive pursuit, and heroes who interpret possession as devotion.
5. 5000 Nights of Obsession by Drethi Anis
Why readers love it
The title is not exaggerating.
This is a story about obsession that has had years to grow, distort, and consume everything around it.
The male lead is jealous, controlling, psychologically intense, and incapable of treating the heroine like someone whose choices exist independently of his desires. The relationship includes blackmail, captivity, possessiveness, and a level of fixation that feels deeply personal and profoundly unhealthy.
This is not a recommendation for readers who need a secretly tender stalker.
It is for readers who want an obsessive hero who is controlling even when the story is not trying to make his behavior comfortable. Available descriptions identify the book as a contemporary dark stalker romance involving blackmail, captivity, somnophilia, obsessive jealousy, and nonconsensual marking.
Spice level: 5/5
Darkness level: 5/5
Trigger warnings: Stalking, captivity, blackmail, somnophilia, coercion, nonconsensual marking, emotional abuse, extreme jealousy, possessive control.
Best for readers who liked: Aero’s complete disregard for boundaries and the terrifying certainty with which he claims the heroine.
6. Unholy Vows by Mila Kane
Why readers love it
Unholy Vows trades Aero’s masked-stalker energy for an older Italian mafia boss who sees an innocent woman enter his world and decides she will not be leaving it.
Renato is jealous, possessive, powerful, and dangerously certain that he knows what is best for Charlie. Their story includes forced marriage, an age gap, criminal danger, obsessive protection, and a hero who turns possession into a permanent arrangement.
The religious language and “innocent lamb entering the wolf’s world” imagery give the story a deliciously sinful atmosphere, even though the central conflict is mafia rather than church-based. The publisher describes it as an enemies-to-lovers romance involving a young woman trapped in the world of a brooding mafia boss who refuses to let her go.
Spice level: 5/5
Darkness level: 4/5
Trigger warnings: Forced marriage, kidnapping, stalking, mafia violence, age gap, birth-control tampering, breeding themes, possessive behavior.
Best for readers who liked: Obsessive claiming, innocence-versus-corruption imagery, violent protection, and heroes who make permanent decisions for the heroine.
Make Your Next Dark Romance Binge More Comfortable
Books like That Sik Luv are rarely “just one more chapter” reads. If you tend to read in bed for hours, a supportive backrest can make the experience much more comfortable than stacking regular pillows behind you.
The Husband Pillow Reading Pillow with Arms has a tall back, supportive arms, an adjustable shredded-memory-foam fill, and a removable neck roll. It is designed to keep you sitting upright while reading, watching television, or settling in for an especially unhinged dark-romance marathon.
Perfect for: Late-night reading, Kindle binges, book-club weekends, and recovering emotionally after Aero destroys your standards.

7. Church. by Stylo Fantôme
Why readers love it
Do not let the title convince you this is a conventional religious romance.
Church. is a psychologically dark story about damaged people, unstable desire, mental illness, destructive attraction, and characters who are drawn to the most dangerous parts of one another.
The story feels grimy, volatile, and unpredictable. Instead of presenting darkness as a stylish accessory, it places readers inside the minds of people whose understanding of love has been warped by trauma.
This is a strong recommendation for readers who liked the psychological instability in That Sik Luv and want another book where attraction feels like the beginning of a breakdown.
Romance.io classifies the novel as dark romantic suspense and tags it with mental illness, abuse, self-harm, trauma, dangerous characters, and explicit content.
Spice level: 4/5
Darkness level: 4.5/5
Trigger warnings: Mental illness, self-harm, past sexual abuse, emotional abuse, violence, toxic relationships, trauma, destructive behavior.
Best for readers who liked: Unstable characters, psychological unease, morally damaged love interests, and relationships that feel combustible.
8. Sanctum of Sins by Scarlett Noir
Why readers love it
Sanctum of Sins combines religious conflict, exile, dangerous secrets, BDSM, and intense devotion.
The male lead has been rejected by the Church, while the larger story explores what happens when institutions that claim moral authority become sources of judgment, trauma, and control. The romance leans more toward dark obsession and forbidden devotion than traditional stalker horror, but the religious imagery makes it a natural choice for this list.
The book is especially appealing for readers who enjoy watching characters reject the roles they were assigned and create their own definitions of sin, loyalty, and salvation.
Romance.io describes the hero as having been exiled by the Church and categorizes the story with religious trauma, BDSM, bondage, danger, survival, and dark contemporary romance.
Spice level: 4.5/5
Darkness level: 3.5/5
Trigger warnings: Religious trauma, violence, bondage, BDSM, institutional rejection, emotional abuse, survival situations.
Best for readers who liked: The collision of faith, sexuality, punishment, and dangerous devotion in That Sik Luv.
9. Silent Vows by Patience Lee
Why readers love it
Silent Vows takes place inside an isolated, technology-free religious community governed by rigid rules and powerful Elders.
The heroine’s crime is reading a forbidden book and questioning the authority surrounding her. Her defiance places her in danger, but it also awakens an intense obsession in a man whose discipline has been built around repression.
This is a slower and more emotionally restrained recommendation than That Sik Luv, but the atmosphere of purity culture, forbidden knowledge, spiritual control, and desire breaking through obedience makes it an intriguing thematic match.
The published description identifies it as a slow-burn dark romance set in a fictional religious community, featuring forbidden reading, institutional control, and a hero whose devotion becomes all-consuming.
Spice level: 3.5/5
Darkness level: 4/5
Trigger warnings: Religious oppression, forced marriage or relationship expectations, misogyny, punishment, emotional abuse, isolation, controlling authority figures.
Best for readers who liked: Repressed desire, oppressive religious environments, forbidden rebellion, and obsession hidden beneath rigid discipline.
10. Lessons in Sin by Pam Godwin
Why readers love it
Father Magnus Falke has built his identity around control.
Then a defiant young woman begins challenging every rule he relies on.
Lessons in Sin is a dark, taboo priest romance filled with repression, punishment, temptation, anger, and the slow destruction of spiritual boundaries. Magnus is not Aero, but he possesses the same sense of suppressed darkness waiting for the right person to drag it into the light.
The book’s own description centers on a priest whose “dark nature” is awakened by a rebellious heroine, creating a romance in which pain, desire, authority, and sin become dangerously tangled.
Spice level: 5/5
Darkness level: 4/5
Trigger warnings: Priest/student relationship, age gap, power imbalance, religious trauma, punishment, BDSM, emotional manipulation, institutional authority.
Best for readers who liked: Blasphemous desire, religious repression, dominant heroes, punishment, and the deliberate corruption of innocence.
11. Dead Man Walking by Giana Darling
Why readers love it
Priest McKenna is not a priest in the traditional sense.
He is an enforcer, a killer, and a man described as the human embodiment of death.
Bea is fascinated by him long before she should be. Rather than running from the darkness, she wants to understand it, touch it, and discover whether someone seemingly empty can feel anything for her.
This is an excellent recommendation for readers who loved Aero because he was genuinely violent—not merely rude, dominant, or morally gray. Priest is cold, dangerous, emotionally detached, and capable of brutality.
The author describes the novel as a dark, bloody, suspenseful romance, while retailer summaries present Priest as a broken enforcer whose heroine is determined to find the remaining humanity inside him.
Spice level: 4/5
Darkness level: 4.5/5
Trigger warnings: Murder, graphic violence, age gap, biker-club violence, emotional detachment, blood, criminal activity, sexual content near violent situations.
Best for readers who liked: A hero who feels genuinely lethal, death imagery, obsessive attraction to dangerous men, and heroines who approach the darkness instead of fleeing it.
12. Bait by Jade West
Why readers love it
One of the most memorable elements in That Sik Luv is the predator-and-prey tension.
Bait places that dynamic at the center of the relationship.
The heroine seeks out a stranger online to help her enact a dark fantasy. She runs. He hunts. The arrangement is supposed to last one night, but emotional attachment complicates a scenario built around fear, danger, and carefully negotiated loss of control.
Unlike many books on this list, the central chase fantasy is deliberately requested. That makes Bait a useful recommendation for readers who loved the pursuit and primal energy of That Sik Luv but want clearer consensual framing.
Google Books describes the setup as a stranger becoming the hunter while the heroine becomes the bait, and Romance.io categorizes the novel with dark romance, primal play, and chase-play themes.
Spice level: 5/5
Darkness level: 3.5/5
Trigger warnings: Consensual non-consent, primal play, chase scenes, past trauma, violence, fear-based sexual scenarios, explicit content.
Best for readers who liked: The chase, predator energy, physical fear, dominant pursuit, and “run because I want you to catch me” tension.
13. Lovely Violent Things by Trisha Wolfe
Why readers love it
Lovely Violent Things is for readers who want darkness that feels intelligent, poetic, obsessive, and psychologically elaborate.
The hero’s fixation is not simple lust. He intellectualizes it, studies it, and transforms the heroine into a muse for his darkest impulses. Their connection is tangled in violence, manipulation, murder, and an atmosphere that makes romance feel like an experiment conducted by deeply disturbed people.
This is the second book in the Hollow’s Row series and should be read in order.
Reader descriptions repeatedly emphasize the hero’s obsessive need for Halen and the series’ calculated, psychologically intense approach to violence.
Spice level: 4/5
Darkness level: 5/5
Trigger warnings: Murder, serial violence, psychological manipulation, obsession, trauma, blood, disturbing imagery, coercive behavior.
Best for readers who liked: Aero’s intelligence, theatrical darkness, fixation, philosophical monologues, and ability to make violence feel intimate.
14. Pray for Scars by K.V. Rose
Why readers love it
This is one of the darkest recommendations on the entire list.
Pray for Scars explores cult violence, trafficking, sacrifice, criminal power, and characters who have already been damaged far beyond the limits of a conventional romance.
It is the second book in the Unsainted series and must be read after the first installment. This is not a book to choose casually or read without checking detailed warnings.
The connection to That Sik Luv comes from its pseudo-religious cult, sacrificial imagery, weaponized faith, and refusal to soften the ugliness of the world surrounding its characters. Reader summaries describe the heroine as a trafficking survivor connected to an elite pseudo-church that uses human sacrifice.
Spice level: 4/5
Darkness level: 5+/5
Trigger warnings: Child sexual exploitation, trafficking, cult abuse, human sacrifice, rape, torture, extreme violence, psychological trauma, death.
Best for readers who liked: Religious horror, brutal cult dynamics, sacrificial imagery, and books that push significantly beyond mainstream dark romance.
15. The Prophet by Celia Aaron
Why readers love it
After The Maiden exposes the horrors of the Cloister, The Prophet pushes readers deeper into its hierarchy.
This installment expands the corruption, cruelty, manipulation, and power struggles inside the organization. The romance becomes inseparable from survival as characters attempt to navigate a system designed to control their bodies, beliefs, and futures.
Including both The Maiden and The Prophet is intentional. Readers who choose this trilogy are not simply getting a romance with religious imagery. They are entering a complete story about a powerful cult, institutionalized abuse, rebellion, and the cost of destroying a leader who believes he speaks for God.
The Cloister trilogy consists of The Maiden, The Prophet, and The Church, and the books should be read in that order.
Spice level: 4/5
Darkness level: 5/5
Trigger warnings: Cult abuse, sexual violence, captivity, torture, exploitation, death, misogyny, manipulation, religious trauma.
Best for readers who liked: The larger religious conspiracy surrounding That Sik Luv and want an entire trilogy devoted to destroying a corrupt spiritual empire.
What Makes That Sik Luv Different From Most Stalker Romances?
Plenty of dark romances feature a possessive man watching a woman from the shadows.
Far fewer combine that obsession with religious rebellion.
Aero is not only pursuing Briony. He is attacking the beliefs, authority figures, shame, and moral rules that have shaped her entire identity. His presence forces her to confront whether the institution claiming to protect her is actually another form of captivity.
That is why a standard stalker romance may not completely satisfy readers searching for books like That Sik Luv.
The closest matches need more than surveillance and spice. They need corruption, transformation, psychological warfare, or a hero who becomes the physical embodiment of everything the heroine has been taught to fear.

FAQ: Dark Romance Books Like That Sik Luv
What genre is That Sik Luv?
That Sik Luv is generally described as a dark stalker romance. It also contains psychological-thriller elements, religious trauma, forbidden desire, violence, obsession, and extremely explicit sexual content.
Is That Sik Luv a religious romance?
It uses religion as a major part of the conflict, but it is not a traditional faith-based romance. The story examines religious control, hypocrisy, shame, corruption, sexual repression, and rebellion.
Which book on this list is most similar to That Sik Luv?
For religious corruption, start with The Maiden.
For extreme stalker obsession, choose Penance or 5000 Nights of Obsession.
For blasphemous religious tension, read Lessons in Sin.
For a genuinely violent and emotionally detached hero, try Dead Man Walking.
For predator-and-prey chase scenes, choose Bait.
Which recommendation has the darkest religious cult?
The Maiden and the rest of Celia Aaron’s Cloister trilogy offer the most complete cult-centered story.
Pray for Scars may contain even more extreme material, but it is part of an ongoing series and includes exceptionally disturbing subject matter.
Which book has the most unhinged hero?
That depends on the type of unhinged behavior you prefer.
The hero in 5000 Nights of Obsession is intensely controlling and fixated. Priest in Dead Man Walking is violent and emotionally detached. Lovely Violent Things offers intellectualized psychological obsession, while Honeysuckles provides a more feral, paranormal form of possession.
Are these books as spicy as That Sik Luv?
Several are extremely explicit, especially Honeysuckles, The Anti-Hero, Unholy Vows, Lessons in Sin, and Bait.
However, spice levels are subjective. A book can contain frequent explicit scenes without duplicating the exact tone, kinks, or boundary-pushing content found in That Sik Luv.
Do these books contain happy endings?
Many dark romances ultimately provide a happy or hopeful ending for the central couple, but some recommendations are installments in incomplete story arcs or trilogies.
Always verify whether a book is a standalone before starting. The Maiden, The Prophet, Lovely Violent Things, and Pray for Scars require additional books for the complete story.
Are these books safe for beginners?
Most are not.
Readers new to dark romance may find The Anti-Hero or Sanctum of Sins more approachable than Pray for Scars, The Maiden, or 5000 Nights of Obsession.
For gentler entry points, visit the Soft Dark Romance Books Beginner List.
Why do readers enjoy obsessive dark romance heroes?
In fiction, extreme obsession can create an intensified fantasy of being chosen, desired, protected, or pursued without hesitation.
That does not mean readers approve of equivalent behavior in real relationships. Dark romance provides a controlled fictional space in which readers can explore fear, taboo, power, danger, and desire.
Should I check trigger warnings even if I read That Sik Luv?
Yes.
Being comfortable with one dark book does not guarantee that every other dark theme will be enjoyable. Religious abuse, trafficking, self-harm, cult violence, consensual non-consent, captivity, and graphic torture can affect readers differently.
Consult the author’s official content-warning page whenever one is available.
Final Thoughts
The best books like That Sik Luv understand that the appeal is not simply a possessive hero.
It is the collision of obsession, danger, shame, desire, rebellion, and psychological transformation.
Readers want a man who feels like a threat.
They want a heroine being pulled toward everything she was told to fear.
They want blasphemous tension, corrupted innocence, whispered threats, violent devotion, and the terrible realization that the monster may understand her better than anyone who ever claimed to be righteous.
For the closest religious-trauma match, begin with The Maiden.
For relentless stalker obsession, choose Penance.
For pure forbidden sin, open Lessons in Sin.
And for readers who want to stare directly into the darkest corner of this list and immediately regret asking for something more disturbing?
Pray for Scars is waiting.
