Once upon a time, Andrew had cut out his heart and given it to this boy, and he was very sure Thomas had no idea that Andrew would do anything for him. Protect him. Lie for him. Kill for him. High school senior Andrew Perrault finds refuge in the twisted fairytales that he writes for the only person who can ground him to reality—Thomas Rye, the boy with perpetually ink-stained hands and hair like autumn leaves. And with his twin sister, Dove, inexplicably keeping him at a cold distance upon their return to Wickwood Academy, Andrew finds himself leaning on his friend even more. But something strange is going on with Thomas. His abusive parents have mysteriously vanished, and he arrives at school with blood on his sleeve. Thomas won’t say a word about it, and shuts down whenever Andrew tries to ask him questions. Stranger still, Thomas is haunted by something, and he seems to have lost interest in his artwork—whimsically macabre sketches of the monsters from Andrew’s wicked stories. Desperate to figure out what’s wrong with his friend, Andrew follows Thomas into the off-limits forest one night and catches him fighting a nightmarish monster—Thomas’s drawings have come to life and are killing anyone close to him. To make sure no one else dies, the boys battle the monsters every night. But as their obsession with each other grows stronger, so do the monsters, and Andrew begins to fear that the only way to stop the creatures might be to destroy their creator…

In this fresh-yet-familiar gothic tale―part historical fantasy, part puzzle-box mystery―the worlds of Dracula and Sherlock Holmes collide in a thrilling exploration of feminine power. At the dawn of the twentieth century in Paris, Samantha Harker, daughter of Dracula’s killer, works as a researcher for the Royal Society for the Study of Abnormal Phenomena. But no one realizes how abnormal she is. Sam is a channel into the minds of monsters: a power that could help her solve the gruesome deaths plaguing turn-of-the-century Paris―or have her thrown into an asylum. Sam finds herself assigned to a case with Dr. Helena Moriarty, daughter of the criminal mastermind and famed nemesis of Sherlock Holmes and a notorious detective whom no one wants to work with on account of her previous partners’ mysterious murders. Ranging from the elite clubs of Paris to the dark underbelly of the catacombs, their investigation sweeps them into a race to stop a beast from its killing rampage, as Hel and Sam are pitted against men, monsters, and even each other. But beneath their tenuous trust, an unmistakable attraction brews. Is trusting Hel the key to solving the murder, or is Sam yet another pawn in Hel’s game?
