Tigerstar is in the Dark Forest, as he has been for many moons. However, when he finds an innocent kit there, a unique case, he realizes he must help her find her way to StarClan. Together they embark on a journey, to StarClan and to redemption.

Firestar's life as leader is going smooth; too smooth, in fact, because he's, well... bored. But what happens when his life is jolted as he discovers a mysterious puddle that links him to another world... where all who were thought dead are still alive?

StarClan has trusted Tigerstar to be reborn, without any memories of his old life. But when his past lives create a scheme not even StarClan knows of, what path will Tigerkit choose? Ambition, or loyalty?
