Best-selling author Rick Riordan presents the thrilling conclusion to Roseanne A. Brown's middle grade trilogy about a pre-teen girl who, as half-Slayer and half-vampire, is caught between two worlds.

Serwa Boateng has gone head-to-head with vampires, witches, and even a death god. But now, with the fate of the magical world at stake, she'll have to face her toughest foe yet: her own grandmother.

Finally free after decades of being trapped inside the Midnight Drum, the dreaded obayifo Nana Bekoe seeks the destruction of the Abomofuo. Even worse, she has Serwa's father under her thrall. Now, the hunters have become the hunted, as the Slayers' defenses are powerless in the face of an enemy who has access to all their secrets.

Serwa's only chance of saving her father might just lie with the Keepers, an organization whose powers exist outside the normal rules of magic. But the Keepers are even more secretive than the Abomofuo, and finding them will require Serwa to trek across the United States. At least she has her friends by her side for the journey . . . friends who currently hate her guts. The survival of everything and everyone Serwa has ever loved hinges on her completing this final hunt without losing herself in the process.

Serwa Boateng has been a Slayer. She's been a vampire. But now, it's time for her to become something else entirely: a hero.
