Kind of an odd question but here goes. My wife is a teacher for teens with challenges - mostly emotional ones. She helps them keep up with studies while they are getting help for these needs. One of her students asked about reading Watchmen - he had seen the movie. I hesitated to say that was a good idea, she's going to read it more herself to get a better idea - but part of me remembers reading Stephen King in high school and they are certainly close in content.
She thought that graphic novels might be nice for them to have since they do a fair amount of free reading and they are usually fairly quick reads and are a nice escape from the setting they are in. I did give her my copy of Runaways vol 1 and may give her a few others I have after read them over again for content. But in the meantime what would be some good books to pick up to keep in a classroom setting like that - where teens need a bit of escapism, nothing heavy handed or hugely emotional, and that generally avoid touchy things like rape, suicide, heavy drug use, etc.
