Firestar's dreams are disturbed by wailing cats and feelings of fear and sadness. He finds out that the wailing cats are SkyClan cats, a lost Clan that was chased from the forest many years ago. The Clan has been forgotten by everyone else, because it has been such a long time since it was destroyed. Firestar realizes that he must go on a quest to rebuild this Clan, and he takes his mate, Sandstorm with him.
