After the sharp-eyed Jay and the roaring Lion, peace will come on Dove's gentle wing.

Three ThunderClan cats, Jayfeather, Lionblaze, and Dovepaw, are prophesied to hold the power of the stars in their paws. Now they must work together to unravel the meaning behind the ancient words of the prophecy.

As Jayfeather tackles his new responsibilities as the Clan's sole medicine cat and Lionblaze trains his apprentice in the ways of the warrior cats, Dovepaw hones her own unique ability and tries to use it for the good of ThunderClan. But the dark shadows that have preyed on the Clan for many moons still lurk just beyond the forest.

Soon a mysterious visitor will walk in one cat's dreams, whispering promises of greatness, with results that will change the future of ThunderClan in ways that no cat could have foreseen.

The end of the stars draws near. Three must become four to battle the darkness that lasts forever.

With a divided StarClan driving a treacherous rift between the four warrior Clans, the spirits of the Dark Forest are gaining strength. Ivypool’s role as a spy becomes more dangerous with each passing day, and Dovewing is haunted by nightmares about the mountains. An outsider appears in ThunderClan's midst, spreading discord and pushing the Clans further apart. As tensions mount and Clanmates turn against one another, the warrior cats will be forced to choose whose word they can trust—before it's too late.
