The other girl - Sarah Miller

Being in Gid's head by the way . . . it's different from being able to read his mind. I can read his mind, but I think of that as something you can turn on and off. I am inside his head every waking minute of our lives.

Molly McGarry seems to have it all - she's smart, she attends the prestigious Midvale Academy prep school and she's finally got the guy of her dreams, Gideon Rayburn. But now everything's changing.

Molly and Gid got together in a very unusual way, when Molly mysteriously entered Gid's mind, and so could 'guess' what he was thinking and exactly what he wanted. This gave Molly one-upmanship over Cullen and Nicholas, Gid's debauched and rebellious room-mates, who pressure Gid and prefer him single.

By some bizarre twist of fate, Molly suddenly leaves Gid's mind and enters the mind of Pilar Benitez-Jones, possibly the hottest girl in the world, and definitely not someone whose head she wants to be inside. Pilar flirts with Gid. A lot. And she appears to be the shallowest and most spoilt rich girl on campus. No longer inside the head of her crush, Molly feels her life is spiralling out of control. Gradually Molly realises that being inside Pilar's head has its advantages as she tries to influence Pilar for her own schemes and to salvage her grades - with ensuing chaos.
