Lacey Linden has gotten good at hiding the truth of her life—a depressed mom, a crumbling house, and bills too big to pay. In school, she's a girl with a ready smile and good grades, but at night, Lacey spends her time dreaming up ways to save her family. On a get-cash-quick trip to the flea market, she stumbles over a music box that seemingly begs her to take it home. She does, only to find it is inhabited by a gorgeous "genie." He offers her a month of wishes, one per day, but there's a catch. Each wish must be humanly possible. Grant belongs to a league of supernatural beings, dedicated to serving humans in need. After two years of fulfilling conventional wishes, he's one assignment away from promotion to a new job with more challenging cases. His month with Lacey is exactly what he expects and nothing like he imagines. Lacey and Grant soon discover that the hardest task of all might be saying goodbye.
