Man, why has no one said any of the books from the Redwall series?
But seriously, Mossflower by Brian Jacques is probably my favorite book of all time.
Also, Eragon sucks, end of story. The guy who wrote it has no talent, and it was only made popular because of the fact he's young, even though he's terrible at writing and couldn't come up with an original story. I will applaud him for actually finishing a novel, but still, that achievement doesn't excuse the suck.
