About this book

An instant New York Times and USA Today bestseller! From New York Times bestselling author RuNyx comes Enigma, a twisted Hades and Persephone meets scorching dark academia romance―a tale of love and obsession between two rivals. There are secrets she must uncover. There are secrets he must keep. Salem Salazar is fascinated with death. The black sheep of her scandal-ridden, wealthy family, she arrives at Mortimer University as a legacy on the hunt for answers about what happened to her perfect, older sister. There, she discovers that her sister is far from the only girl to have gone missing at Mortimer. Salem will do anything to discover what dark forces are killing Mortimer's students...even if it means using herself as bait. And Cazimir van der Waal has caught her scent. The mysterious artist and teaching assistant has a dark past, a hidden agenda, and a ravenous appetite for a beautiful, golden-eyed girl who seems determined to risk her life. Where she is ice, he is fire. Where she is organization, he is chaos. Where she is precision, he is passion. Together they are explosive--their fates linked as secret societies and death stalk them both. Enigma is a sensual, epic love story for those who also crave the frightful, the puzzling, the suspenseful, the dangerous and the dark. Welcome to Mortimer.
