The winds have shifted in the Beyond. It's summer, and that should mean warmth, fish and meat, but blizzards rake the land and the caribou and moose that the wolves hunt are vanishing. Famine has arrived in the Beyond, and the strict order among the wolf clans is starting to break down.Worse, there's one wolf thriving on the chaos. He wears a stolen owl battle mask and calls himself the Prophet. There are horrible rumors that instead of helping the wolves survive, he's leading hundreds of them to their deaths. The elite wolves of the Watch send young Faolan and his friend Edme on a desperate mission to bring down the Prophet. But how can the two wolves stop an enemy they can't even find?
