Good Little Wolf by Nadia Shireen (Paperback, 2011)
Once upon a time there was a wolf called Rolf - a good little wolf who liked baking cakes and was always kind to his friends. But real wolves aren't supposed to be good - they're supposed to be BIG and BAD. Can a good little wolf still be a real wolf? And will Rolf discover there's something big and bad lurking inside him after all?
