Another one off of NPR's Ultimate Backseat Bookshelf.
I've tried to read Watership Down several times, and I finally finished it! I used to watch the movie over and over as a kid even though it scared the crap out of me. I was talking to a coworker and we both agree that you could read the first half of this book and then leave the rest (like Little Women). I got really nervous at the end and had to spoil it for myself before I could finish (I waited several months before reading the last three or four chapters...).
It's very well written. I love the world building (I was expecting something similar when I started The Warriors series by Erin Hunter and was sorely disappointed). And this is from someone who doesn't love animal fantasies (I have no idea how I'm going to get through Redwall). It was worth the time it took to read.
