help!

I'm planning a program at work with another librarian, and I'm asking for your help. It's going to be a teen book club. Each month we'll read the book and then when they get together, they will create a facebook news feed for the plot. This whole idea was brought about when Linette showed me this. Then I looked around for other books and found this one. As they come up with things, one of us will be typing them up and then we'll print them out so each participant can have a copy. I've got quite the collection of facebook icons (status update, groups, events, etc.) edited and stuck in a word doc. We're looking for books with a fair amount of characters. We'll be breaking the group up by character--depending on the size of the book club that month, either small groups of single people will be doing one character. The first month is going to be Twilight, in order to entice people into coming. And we can have status updates like:

• Edward is brooding.
• Bella fell down. Again.
• Bella hates this truck!
• Bella has decided that Edward is a vampire.
• Edward is going to show Bella what happens in the sunlight. [Of course, if I were doing this one, I would make it say "Edward sparkles!"]
  

So, what books would you suggest? We've got a small list of possibles so far.

• Fat Kid Rules the World
• Stoner and Spaz
• Speak
• Doing It--probably not
• Finding Lubchenko
• Rules of Survival

Nothing terribly long, so please no one suggest Uglies. :)
