When I was a school librarian Watership Down was one of the books I most recommended to students.
My sixth grade English teacher told me it was trash, along with Jonathan Livingsting Seagull.
I treasured reading it in high school. I still remember most of it by heart. A lot of good v evil to take from it. A lot of not settling for what you are told by those in authority. Form strong trusting bonds with peers to overcome just about anything. Great book.
