When the cat Mooncloud has her kits, she is unaware that one of them has a destiny like no other. Soon after the kits are born, battles break out among the Clans. To top it all off, StarClan sends the Medicine Cats a mysterious omen. "War will rage on among the Clans. Battles will be fought with claws and teeth, but peace will lie in the heart of a clover's gentle leaf."
