New York, 1926. Reapers - once-human vampires - stalk the shadows.
The Saint family has reigned over the city for years, protecting its inhabitants through their thriving reaper-hunting enterprise. But reluctant heir Elise Saint faces a chilling threat: the Harlem reapers want her dead.
When new reaper Layla Quinn was turned, she lost her parents, the protection of the saints, and her humanity - and she'll never forget how Elise Saint betrayed her.
Now reapers are inexplicably turning part-human, leaving grisly murders in their wake. And when Layla is framed for one of these attacks, the Saint patriarch offers a deal she can't refuse: work with Elise to discover how the murders might be linked to rumours of a reaper cure.
Once close friends, now bitter enemies, Elise and Layla explore the city's underbelly, confronting their feelings for one another and uncovering sinister truths that threaten both reapers and humans alike.
