This past January, The Elders’ Quest, kicked off the brand-new Changing Skies arc, introducing us to Moonpaw and reaquainting us with the perspectives of Leafstar and Tawnypelt as the Clan faced a new threat from twolegs. Now, we’re excited to reveal the cover, title, and blurb for the second book in Changing Skies, titled Hidden Moon! We’re delighted to show you the wonderful new cover for this upcoming tale, written by Clarissa Hutton and featuring Starlingpaw in the front and Crowfeather and Nectarsong above him, as well as the official blurb. Keep an eye out for this one hitting your local bookstores November 4th, 2025.

Erin Hunter’s #1 bestselling Warriors series continues with the second book in the Changing Skies arc, as the Clans continue to navigate an ominous prophecy that foreshadows the end of the cats’ connection to StarClan.

Still healing from an accident that almost killed her, Tawnypelt is eager to share the message she received from StarClan about a “great peril” looming over the clans. But her vision is dismissed by her son and leader, Tigerstar, leaving Tawnypelt with no choice but to take action on her own.

Racked with guilt that he caused his father’s death, Starlingpaw is determined to atone for his mistake. His chance comes when Tawnypelt warns him of a “two-faced cat” intent on destroying the clans. Believing himself uniquely suited to find this cat and stop them, Starlingpaw seizes on the opportunity to prove that he is an asset, and not a liability, to SkyClan.

Moonpaw is settling into her role as a ThunderClan apprentice, even as she continues to grapple with the voice in her head. But the more she tries to ignore the voice, the louder—and angrier—it grows.

Meanwhile, Twolegs have set their sights on the Moonpool, preventing the Clans from reaching StarClan. Will the cats find a way to reach their ancestors before all is lost?
