Shreve, Susan. Kiss Me Tomorrow. 2006.
Blister (aka Alyssa) and her best friend Jonah are just starting Junior High. He dumps Blister so he can follow around the "cool" kids. These kids aren't the best behaved kids in school and they end up leaving Jonah with a bunch of shoplifted electronics equipment. Blister knows Jonah would have never steal anything. After he runs away, Blister knows where to find him and tries to help him stay hidden. Meanwhile, her mother and her boyfriend decide to move into a house together, which just so happens to be across the street from Jakob, one of the guys that left Jonah to take the rap for the shoplifting.
This was a good middle school title. Recommended for middle school girls.
