Erin Hunter’s #1 bestselling Warriors series continues with the third book in the Changing Skies arc. Two cats--an elder and an apprentice--believe that only they can save the Clans from certain destruction.

Moonpaw finally confesses to her Clanmates that her dead sister has been torturing her in her mind, and the Clan rallies around her in support. But as Moonpaw grows closer to Goldenpaw, her sister's threats become more ominous, and even turn bloody. Moonpaw worries she's a danger to her entire Clan. Would Thunderclan be better off without her?

Tawnypelt is sure that the prophecy she received from Bluestar is a dire warning--and she believes that only the Elders can see the Clans through the oncoming danger. Frustrated with his mother, Tigerstar bans her from speaking of the prophecy, so Tawnypelt takes refuge in ThunderClan. She begins to wonder if her true place is in the Clan of her birth.

Amidst all this, Starlingpaw grows bolder in his belief that he alone must save the Clans. But can an apprentice really hold the key to their salvation?
