About the book: 2003 / During the war between the clans, the Shadow Tribe expelled the Wind Tribe cats from their territory, which upset the balance in the forest. To restore justice and the established order, Bluestar gives Fireheart and Graystripe a responsible and dangerous assignment - to find and return the WindClan cats home. But not everything is calm at home either - alien tracks were found on the borders of the tribe, and not all kittens will probably survive the coming winter..
