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?

From USA Today bestselling author Cassandra Khaw comes The Salt Grows Heavy, a razor-sharp and bewitching fairytale of discovering the darkness in the world, and the darkness within oneself. You may think you know how the fairytale goes: a mermaid comes to shore and weds the prince. But what the fables forget is that mermaids have teeth. And now, her daughters have devoured the kingdom and burned it to ashes. On the run, the mermaid is joined by a mysterious plague doctor with a darkness of their own. Deep in the eerie, snow-crusted forest, the pair stumble upon a village of ageless children who thirst for blood, and the three 'saints' who control them. The mermaid and her doctor must embrace the cruellest parts of their true nature if they hope to survive.
