Ruffleclaw is a memorable character, which you would hope that a monster would be. He is overwhelmingly disgusting and rude, with very few redeeming qualities. Readers who like gross-out humor and fantastical characters will likely enjoy Ruffleclaw. If you are not into monsters, you might want to pass on this book.
This book is engaging and easy to read - it would be a great choice for younger readers in the 8-11 year old group.
