My 11-year-old son is struggling with new friendships at a new school. He is very loyal to his friends, who can be difficult and get in trouble, and that can lead him into trouble. I would like to find teen fiction books that address these kinds of situations -- for example, where the kids have friends, and those friends are imperfect and do bad things, and kids have to decide how they will respond. I'd also be interested in teen fiction that addresses issues of troublemaking, independence or loyalty more generally. He is a fairly mature reader for his age, so books aimed at 10-14 year olds might fit the bill.
