Rescued by Aster, a warrior with rabbit ears, he finds her struggling tribe forced to trade precious food for fire. He can make his own. With only 47 days until the first snow, Rowan turns survival knowledge into clean water, medicine, weapons, and hope. But every breakthrough threatens the tribes controlling their lives. As Aster becomes his closest ally, this ordinary human must learn to lead, forge unlikely alliances, and protect the people who have finally given him a reason to call somewhere home.
