My Fake Boyfriend Is Better Than Yours — Kristina Springer

Seventh grade was supposed to be fun, but Tori is having major drama with her BFF, Sienna. Sienna changed a lot over the summer -- on the first day of school shes tan, confident, and full of stories about her new dreamy boyfriend. Tori knows that shes totally making this guy up. So Tori invents her own fake boyfriend, who is better than Siennas in every way. Things are going great -- unless you count the whole lying-to-your-best-friend thing -- until everyone insists Tori and Sienna bring their boyfriends to the back-to-school dance.
