Perhaps the quintessential summer camp story, if a little mired in period (John Garfield!). I never went to camp, but I'm fairly certain that if I had, I'd have been a lot like Laura.
I loved Camp books! In fact, I wrote one myself in 7th grade, a hodge-podge of every summer camp book I had ever read. I wish I still had it, I bet it was HILARIOUS.
