James and the Gigant Peach
I love reading foreign childrens books. Apart from being entertaining, they give you the moral values and ideals of a people in a nutshell, and you get an idea of how people think in that country.
That doesn't necessarily mean I'd copy said behaviour, though. I'd rather not eat green eggs and ham, for example. As a general rule, they won't agree with you once they turned that particular colour.
In that case, I'd recommend pretty much everything by Roald Dahl, his kids' books, and grown ups' books!
If you want a good kids' book by an American author I'd suggest The Giver
, by Lois Lowry.
