In order to steal the Midnight Drum and free her powerful grandmother, twelve-year-old vampire Serwa deceptively collaborates with her rival Declan, a Slayer, but joining forces compels Serwa to confront truths about herself she has tried hard to deny.

After a lifetime of fighting creatures of black magic, twelve-year-old Serwa Boateng has just learned a devastating secret: she herself is half vampire! Now not only is she dealing with vampire puberty, she's on the run from the organization of Slayers she trained her whole life to join. Serwa's only ally is her aunt Boahinmaa, an obayifo who urges Serwa to embrace her vampire side. Boahinmaa and her underlings are on the hunt for the Midnight Drum, from which they hope to free Serwa's grandmother. When they learn that the Abomofuo have hidden the Midnight Drum deep within the Smithsonian Museum of African Art in Washington, D.C., what do they do? Stage a heist to steal it, of course! For their plan to succeed, Serwa will have to get close to her rival, a Slayer named Declan Amankwah, without revealing her real nature. Declan gets under her skin like no one else . . . and might just force Serwa to confront some truths she's tried hard to deny.
