On her deathbed, Yani's great-grandmother reveals she has one last story from her past to tell: that of his great-uncle Yakov, who helped her survive the Nazis. It's a story of vampires and werewolves he can scarcely believe—and in the wake of his great-grandmother's death, Yani discovers the story is far from over.

The world of vampires and werewolves isn't a safe place for a human, even one with Yani's unusual family history. With danger at his door, the smart thing would be to run, but much like his great-grandmother, Yani has never been very good at running away—especially with his loved ones and the whole world at stake.
