This book is just wonderful. It's a fairytale. Appropriate for children (nothing horrible happens), but clearly written for adults (or at least older children with an awesomely developed vocabulary).
A little girl goes to Fairyland as one of the "Ravished." Shenanigans ensue. Fairyland is saved (as, of course, it would be - this is a fairytale after all).
Valente's prose, especially in this book, is so very delightful and satisfying. I want to kidnap children just to read this to (my dog, oddly, does not seem to appreciate the word-choices in the passages I read out loud to her).
