Shade is a wolf pup from the Winter Wolves, but she has been cast out due to the gray tint on her white fur, making her resemble the rumoured 'Shadow Wolves' that haunt the fifth toe of the islands that take the form of a wolf's paw. The Main Island that the packs only rarely visit has been made into her home territory. Shade longs to find her birth-pack and be reunited with her mother, but it doesn't seem possible when she's separated by a rough ocean. When she finally makes the attempt, and is swept to the island of the Shadow Wolves, what will happen to this abandoned pup who only wanted to find her home?
