Query: Highly recommended! (for readers about 13+ y.o.)

My dad used to read Roald Dahl books with me when I was a little tyke, and this particular little devil DEFINITELY lives up to its title, so if you're one of those parents who wraps their kid in cottonwool you'll want to pass it up. That being said, I am excessively fond of this book as it gives several traditional fairy tales a deliciously nasty twist that are unforgettable. Language use is about PG-13. If you and your kid are sensible/mature enough to have a sense of humor, you'll enjoy it immensely. My dad has since passed away but one of my many fond memories is that we both got a kick out of this clever little book.
