book club recommendations

Hallo, TQC. It is time to put on your librarian hats again!

A coworker and I will be doing a book club this fall, open to 6th, 7th, and 8th graders. My school is a suburban/semirural school with around 50% free/reduced lunch. My students are just as likely to idolize Lil Wayne as they are to go mudding on a Saturday night. They have a fairly wide range of interests. The 7th grade clamored over The Hunger Games last year and almost everyone read it- so that books out. The sequels are out because my coteacher doesn't enjoy the series. I tend to stick to dystopian and GLBTQ YA lit, so I'd like some opinions from people who read other stuff.

What book do you think we should do for our book club?

[EDIT] Thank you all for the suggestions! I had either read or made note to read almost all of the books you've recommended and didn't even think about them- so thank you for reminding me they exist! (And getting me back on track on my to-read shelf!)
