Tall and lanky, Genie Lowry is only noticed at academic awards assemblies—until the day she turns 17 1/2, when her body changes from flat to curvy—and she finds out she's a real, live genie. Suddenly, every guy at school is paying attention to her, including Pete Dillon, her never-in-a-million-years crush.

But to gain her full powers and keep her new body, Genie has to find a master, and she's not sure if Pete's Master (or Mr.) Right. With help from her dead mother's interactive diary and an imposing mentor with questionable motives, Genie uncovers the family history and genie rules she never knew. She grapples with her new powers and searches for the perfect master as she tries to make her own wishes come true.
