Back in the 60's when student leaders had as one of their standard chants "Don't Trust Anybody Over 30", they were specifically refereing to English teachers who, trying to relive their glory days assign insipid, heavy handed books like this that beat readers over the head with symbolism to make up for basic lack of plot or any entertainment value. The assigning of this book to students, rather than achieving the teachers of goal of trying to instill a 60's mindset in their studetns will more probably result in loathing for that teacher and in the English language as a whole for producing words that could be put together in so unappealing a form as this story.
The book is typical, misfits and bedwetters, go to camp, get picked on, see Buffalo slaughtered, sneak out, try to let them go, then of course since the author wants to make SURE that we understand the viewpoint that Group A is bad and Group B is good, has one of the children shot while trying to free the buffalo. Yeah, thats worth skipping class for.
Buy this book if you want to become a misfit bedwetting animal activist.
