Promise of the Wolves was a book which I wanted to like, because I enjoy reading animal fantasy books, but unfortunately it was a big disappointment.
When I read this book I couldn't help but wonder if the author had intended to write a young adult fantasy book for adults. This book reminded me too much of Richard Adams' Watership Down, but it lacked the depth and originality of Adams' charming and touching story.
I think that young adults will probably find this book interesting, but adults who have read Watership Down won't like it. In my opinion this book is too light for adults.
If you're looking for good animal fantasy, you should read Richard Adams' Watership Down or William Horwood's Duncton books (and also the two wolf books), because they're enjoyable books - they're much better than this book.
