New York Times bestselling author Hugo and Nebula Award–winning author When Ryan’s crush, Bizzy Horvat, moves into the other half of his family’s duplex, he is swept up into a world of micropotents and micropowers. It becomes Ryan’s job to protect Bizzy from people who want to kill her. Ryan wakes up to find his contractor dad building walls to turn their big old house into a duplex. The family that moves into the other side includes Bizzy Horvat, the pretty girl he has a crush on at school. Bizzy claims her mother is a witch with the power to curse people with clumsiness or, in Bizzy’s case, astonishing beauty. When a bee gets caught in Bizzy’s hair, Ryan acts so quickly and radically to save her from getting stung that he attracts the attention of a group of micropotents—people with micropowers. He soon realizes that Bizzy and her mother also have such powers. It becomes Ryan’s job, with the help of the other micropotents, to protect the Horvats from a group of witch hunters from their native country, who are determined to kill Bizzy, her mother, and all the other “witches”—micropotents—who have gathered to protect them.
