An ominous prophecy shapes the lives of Firestar's three grandchildren, but it remains a secret from everyone--except Jaypaw. He believes that the key to the prophecy lies in the past, with the wild cats that stalk his dreams. While he, Hollypaw, and Lionpaw find themselves drawn to the mountain-dwelling Tribe of Rushing Water for reasons of their own, Jaypaw knows that is where the answers lie. But if they find a way to get there, the three young cats might discover more than they ever expected.
