-->''There will be three, kin of your kin, who hold the power of the stars in their paws...''

''Warrior Cats: Power of Three'' is the third [[MythArc arc]] of the popular ''Literature/WarriorCats'' series by Creator/ErinHunter. Set after the events of the [[Literature/WarriorCatsTheOriginalSeries first arc]] and it's sequel [[Literature/WarriorCatsTheNewProphecy The New Prophecy]], Power of Three focuses on the kits of the heroes of The New Prophecy, who find the long-awaited peace the clans have been waiting for threatened by supernatural forces and secrets from the past.

The series stars siblings [[PowerTrio Jayfeather, Lionblaze and Hollyleaf]]. They are the grandkits of Firestar, leader of [=ThunderClan=] and are believed by him to be [[TheChosenOne the three]], cats said to hold power beyond anything the clans have ever seen. When Jayfeather accidentally obtains this knowledge, he makes it his life's mission to fulfill the prophecy. Meanwhile, vengeful cats from the past search for opportunities to obtain revenge, outsiders arrive to reek havoc among the cats, and the secrets of the past come to light which could gravely affect the future...
