No, is the book really that old? I am sorry to hear the author has died.
Watership Down was very much an fond read despite how violent and dark it could get. It was a grand adventure, our heroes struggling to survive and work together, though at first not being so strongly bound together.
Each character was unique and interesting, and it offered quite an insight of what life for a rabbit could be though with some fantastical elements. It allowed for a glimpse at a few different "Societies" in the borrows offer before journey's end.
