These all sound so good! I'm especially interested in The Counselors, and I've been really wanting to read something by Ryan La Sala since I saw him at Chuck Tingle's event. Also, I definitely remember Paula Danziger's name from when I was growing up, though if I ever read any of her books, I can't recall which now.

Two favorite summer camp films of mine are Wet Hot American Summer and The Addams Family Values (camp is only part of the story, I know, but a significant one!).
