A truly magical new animal story from the author of the hugely popular Frank the hamster series. The wolf was enormous. Its ravenous jaws were open wide, its eyes glared fire. When Sam's aunt rescues a lost dog, Sam knows that something incredible is going to happen. Jenny the Jack Russell may be a stray, but she is no ordinary dog. Jenny is more special than Sam could ever imagine... But Jenny is in danger, and now Sam, Jenny and a gang of fellow runaways face an extraordinary journey. The sky wolves are on their trail, and they won't stop until the rest of the world is destroyed. A gorgeously written, mystical adventure that will appeal to fantasy and animal fans alike from 9 years upwards.
