As Shadowclan slips farther away from the warrior code, Batwing and Dawnspirit struggle to keep the four clans in the balance. However the only way to save the forest is to conquer their fears, confront their past, and embrace their bloodlines in one battle against not only the darkness which resides in Shadowclan but also the lies and secrets which are slowly destroying the forest

Bat has just joined Thunderclan, but danger has been stalking her and many wish her dead. Secrets of the past that have never been uncovered haunt her clanmates, struggling to stay hidden, and rivalries that have deep roots, deep enough that they may never be set free, threaten the forest. She soon realizes that her life is in danger, and those that she loves will pay dearly.

When Batwing tells Nightclaw about how Crookedwhisker has become the leader of Shadowclan, Nightclaw reveals to her his dark past and how much danger this puts the clans in. Meet young Nightpaw as he goes on a dangerous quest to find and meet his destiny.

Jani was placed with a curse to talk to animals and roam the night as a cat. Hardly use to this life, Jani meets the clans, who are less than friendly to her at first. But soon, she is thrown into a dark battle, which not even StarClan can fight.

She made a promise she couldn't keep. But she made it nonetheless. A young shecat and her Clan are threatened by the return of an ancient evil, and it's up to the Guardian of the Moon Tree to guide her past the obstacles she must face: Life or Death.
