The beginning of Cracked Up to Be starts:
Four years, two suicides, one death, one rape, two pregnancies (one abortion), three overdoses, countless drunken antics, pantsings, spilled food, theft, fights, broken limbs, turf wars -- every day, a turf war -- six months until graduation and no one gets a medal when they get out. But everything you do here counts."Mean Girls" camp, either. It's physical violence, overdosing, psychiatric evaluations, emotionally absent parents.
I thought both of these books were really good. Protagonists generally well-formed, complex situations where nothing is black and white. Definitely worth reading. I know they're not non-fiction works, but I felt they were probably realistic. Sure put my own (comparatively pain-free) high school experience into perspective.
