It's been years since I've read a Roald Dahl book, I don't remember how old I was when I read this one, but besides Matilda this one has always been one of my favorites. The category for this selection was a banned or challenged book. I read that it was banned/challenged because:
Too mature for the intended audience
Teaches poor moral values
I found the book delightful. I don't think that it teaches poor moral values at all, I can understand the Cannibalism, but honestly it's giants, not Hannibal Lecter. I suppose Hansel and Gretel is challenged as well for these reasons.
It was a quick read and I think that I'll have to go out and buy Matilda soon.
