If Cluster left you wanting more books with messy attraction, obsessive tension, morally gray love interests, and that “this is probably a terrible idea but I need one more chapter” feeling, this list is for you.
These dark romance books lean into danger, control, obsession, taboo tension, psychological intensity, and characters who do not love gently. Some are mafia, some are gothic, some are stalker-coded, some are why-choose or bully-adjacent, but all of them have that same addictive, chaotic pull.
Content note: Dark romance can include heavy themes. Always check full trigger warnings before reading.
1. Nicky the Driver
Author: Cate C. Wells

Spice level: 4/5
Darkness level: 4/5

Best for readers who liked: Obsessive heroes, mafia tension, and emotionally messy devotion.
2. Insatiable
Author: Leigh Rivers

Darkness level: 5/5
Trigger warnings: Violence, trauma, stalking/obsession, toxic relationship dynamics.
Best for readers who liked: Possessive heroes, high spice, and emotionally chaotic dark romance.

3. Phantasma
Author: Kaylie Smith

Spice level: 4/5
Darkness level: 3.5/5
Trigger warnings: Death, violence, blood, grief, horror elements.
Best for readers who liked: Dark games, gothic mansions, morally gray love interests, and paranormal danger.
4. Nightshade
Author: Keri Lake
Why readers love it: This one is lush, gothic, eerie, and emotionally intense. It is slower and more atmospheric than some dark romance books, but the payoff is rich if you love tortured characters, secrets, and a romance that feels cursed.
Spice level: 4/5
Darkness level: 4/5
Trigger warnings: Violence, grief, trauma, death, gothic horror themes.
Best for readers who liked: Gothic dark romance, tortured heroes, and mystery-heavy plots.
5. Infernium

Spice level: 4/5
Darkness level: 5/5
Trigger warnings: Psychological trauma, violence, horror imagery, captivity themes.
Best for readers who liked: Dark gothic suspense, damaged characters, and disturbing secrets.

6. Juniper Unraveling
Author: Keri Lake
Why readers love it: This is dystopian, brutal, emotional, and survival-driven. It is a good choice if the thing you loved about Cluster was not only the romance, but the feeling that everything around the characters is collapsing.
Spice level: 3.5/5
Darkness level: 5/5
Trigger warnings: Violence, death, dystopian horror, trauma, survival themes.
Best for readers who liked: Dark romance with plot, danger, and apocalyptic tension.
7. Dirty Bad Wrong
Author: Jade West

Spice level: 5/5
Darkness level: 4/5
Trigger warnings: BDSM, humiliation kink, trauma, emotional distress, intense sexual content.
Best for readers who liked: Extreme spice, broken characters, and messy healing.
8. Priceless
Author: Miranda Silver
Why readers love it: This is toxic college romance with obsession, power imbalance, humiliation, and emotional confusion. It is not soft. It is not clean. But it is very addictive if you like morally complicated dynamics.
Spice level: 5/5
Darkness level: 4/5
Trigger warnings: Humiliation, degradation, power imbalance, toxic relationship dynamics.
Best for readers who liked: Dark college romance, shame, obsession, and messy consent dynamics.
9. The Doctor
Author: Nikki Sloane
Why readers love it: This one has taboo, forbidden tension, age-gap heat, and a romance that feels like a bad decision from the start. It is more erotic taboo than violent dark romance, but it scratches the same “I should not be this invested” itch.
Spice level: 5/5
Darkness level: 3/5
Trigger warnings: Age gap, taboo relationship, power imbalance.
Best for readers who liked: Forbidden romance, high spice, and risky emotional tension.
10. Breaking Beth
Author: Jennifer Bene
Why readers love it: This is much darker and more intense than mainstream BookTok dark romance. It leans into captivity, psychological pressure, and disturbing obsession, so it is best for readers who already know they can handle very dark material.
Spice level: 4/5
Darkness level: 5/5
Trigger warnings: Captivity, coercion, psychological abuse, violence, trauma.
Best for readers who liked: Extreme dark romance, captivity plots, and villainous love interests.

11. The Tied Man
Author: Tabitha McGowan
Why readers love it: This one is bleak, emotional, and deeply disturbing in places. It has a very different flavor from trendy mafia romance, but readers who want dark, painful, high-stakes romantic tension may find it unforgettable.
Spice level: 4/5
Darkness level: 5/5
Trigger warnings: Abuse, exploitation, captivity, trauma, violence.
Best for readers who liked: Heavy emotional darkness and survival-centered romance.
12. Black Knight
Author: Rina Kent

Spice level: 4/5
Darkness level: 4/5
Trigger warnings: Bullying, trauma, mental health themes, toxic dynamics.
Best for readers who liked: Elite school settings, bully romance, and damaged heroes.
13. Cruel King

Spice level: 3.5/5
Darkness level: 3.5/5
Trigger warnings: Bullying, manipulation, toxic relationship dynamics, family trauma.
Best for readers who liked: Rich dangerous boys, obsession, and social power plays.
14. Deviant Hearts

15. The Dare
Author: Harley Laroux
