Hollypaw, Jaypaw, and Lionpaw - grandchildren of the great leader Firestar - possess unusual power and talent. But secrets and uncertainty surround them, and a mysterious prophecy hints at trouble to come. The warrior code is in danger, and these three apprentices will need all of their strength to help the Clans survive.

It has been foretold that Jayfeather, Lionblaze, and one other cat will hold the power of the stars in their paws. Now they must wait for a sign from StarClan to tell them which of their Clanmates will complete the prophecy.

The wild cats of the forest have lived in peace and harmony for many moons - but now, strange messages from their warrior ancestors speak of terrifying new prophecies and a mysterious danger. Brambleclaw, a warrior of ThunderClan, may be the cat with the fate of the forest in his paws. Now, he will need all the courage and strength of the greatest warriors to save the Clans.

For generations, four Clans of wild cats have shared the forest according to the laws laid down by their ancestors. But the warrior code is threatened, and the ThunderClan cats are in grave danger. The sinister ShadowClan grows stronger every day. Noble warriors are dying - and some deaths are more mysterious than others. In the midst of this turmoil appears an ordinary housecat named Rusty...who may turn out to be the bravest warrior of them all.

It is a time of peace between the warrior Clans, and all four are thriving. Then Firestar, leader of ThunderClan, discovers a terrible secret: The warrior ancestors of StarClan have lied to him. Firestar must embark on a perilous journey to right their wrong - and nothing will ever be the same again.
