SkyClan has returned to the forest. They are known as LostClan, for they were the Lost Clan. They live in an island in the center of the lake, with tunnels under the lake leading to the Gathering Island.
But prey is gettting smaller and smaller, and the Clans have begun to plan to take LostClan's territory for their own. Will SkyClan be re-thrown out of the forest? In their darkest hour, a prophecy comes to the new LostClan Medicine Cat apprentice, Purepaw;
"The light of the Sky must be retrieved for the Clans to be saved. But fangs and fears forgotton follow the ones who frolic to find it..." Four cats must journey out to find the mysterious 'Light of the Sky,' which is also the hope of The former SkyClan, now under the alias Lostclan, which is located in paradise. Once found, the journeying cats' loyalties will be tested, whether to bring back the secrets or to stay in paradise.
