Query: Great WereWolf Book!

I wasn't sure if I'd like this book when a friend gave it to me. But it hooked me from the first page. Really well written, but DARK. I mean people, these are werewolves, and they do kill and eat people. Excellent storyline, kept me reading, and an unexpected twist at the end of the book surprised me.If you like werewolves, get this book!
