I just re-read Redwall for fun about a week ago. I was really into the series as a 12 year old, and I'm glad to say that it still held up for me. For anyone unfamiliar with the series, its about a medieval(ish) world where animorphic mice, rats, badgers, voles, squirrels, and other assorted animals rule. It isn't groundbreaking kids literature but it is a lot of fun.
