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?
