Erin Hunter's #1 bestselling Warriors series continues with the fourth book in the Changing skies arc. How long can the Clans endure life without StarClan's guidance? Moonpaw, Morningkit and Goldenpaw have made their choice, and there's no going back. But while Morningkit is happy to be free of the cats who judged her, Goldenpaw struggles with his decision. Racked with guilt, Moonpaw is torn between pleasing her mate and placating the sister who refuses to leave her side. Meanwhile, Tawnypelt has finally convinced the Clans to agree to look for a new connection to StarClan. Leading a team of cats to SkyClan's old gorge, she hopes that the Whispering Cave will offer guidance. But as the quest begins to wear on the cats, she worries that the gorge may not hold the answers they seek and that their connection with their ancestors may be gone forever. Punished for speaking out at the last gathering, Starlingpaw fears that he is the only cat in SkyClan who understands what the prophecies mean for them.

With the support of his mother and a few Clanmates, he seeks out a larger role in the Clan, hoping to influence Hawkwing and Leafstar. But will he be able to alter SkyClan's course before the cat from the prophecies appears?.
