The wolves live in the valley in relative peace, the sky is blue, the grass is green, and there is enough food to feed everyone. No one knows what lies outside their haven, yet rumors abound that it is a frozen wasteland, and that the valley is the only habitable place left. When wolves start falling ill from a mysterious disease, there is only one boy who might be able to save them, but first he must leave the valley. (Crossposted on Ao3)
