Molly McGarry is about to learn that the only thing more traumatizing than spending six months trapped in your boyfriend's head is being stuck inside your ex-boyfriend's new girlfriend's head. After Molly dumps Gideon because she thinks he's lusting after some one else, a game of spin the bottle leads to a kiss between Gideon and the beautiful, sexy Pilar Benitez-Jones. Somehow, the kiss knocks Molly out of Gideon's head--and right into Pilar's. Now she's desperate to get Gid back. She uses all her "superpower" to try come between Pilar and Gid, but instead of breaking them up, she seems to be bringing them closer together. Can she stand to be at school with Gid and at the same time be inside the mind of the girl he moved on with? How does Molly win back Gid without letting him know what's going on? And how on earth is she ever going to get out of Pilar's head...?
