Just a quick, YA read, that has some depth to it ... it's always interesting when I read a "kids" book and think about possible book club questions ;)  The characters here are in middle school ... to me, they felt a little older, high school age; with crushes, bullying, community service, football (my middle school didn't have a football team). 

There are 30 chapters, shifting POVS (Chase Ambrose, Shoshana Webber, Joel Webber, Brendan Espinoza, Aaron Hakimian, Bear Bratsky, Kimberly Tooley) ... Chase, Shoshana and Brendan are the main characters. All the POVs are 1st person, present tense. All very conversational in tone. In the audio version, there were different narrators for the various POVs. 

I remember a TV show with a similar premise ... Samantha Who, starring Christina Applegate. I think I only got around to watching a few episodes, but the same idea; an accident, amnesia, and a changed person who can't quite believe what a jerk they were before. It brought up some interesting questions. CAN a person change like that? What are the expectations to those who were wronged before? Shoshana's parents and Joel, while both believing Chase is different than he was, still can't  just "forgive and forget" the past. Should they? 

A good book to address some of the issue of middle/high school kids, the bullying, attempts to fit in, expectations/judging, etc. Nice to have some redemption.
