The launch of a brand-new arc in Erin Hunter's #1 bestselling Warriors series find the Clans navigating an ominous prophecy that foreshadows the destruction of the Moonpool, and the end of the Cats' connection to StarClan.
As Leafbare approaches, a new danger threatens the Clans. Twoleg construction has encroached on Clan territory, poisoning the stream and making prey especially scarce for SkyClan. Meanwhile, their leader, Leafstar, is struggling with a loss of vision while trying to maintain authority over a Clan that increasingly doubts her ability to lead.
In ShadowClan, Tawnypelt senses peril as the Twoleg construction threatens the Moonpool, but she can't get anycat, especially her son, TigerStar, to listen. Frustrated with the younger cats who don't respect her, she decides to take matters into her own paws.
In the midst of the chaos, Moonpaw, an apprentice struggling to understand the mysterious voice in her head, thinks that she might be having visions. But the voice becomes increasingly sinister, and Moonpaw wonders if it's a sign of darkness on the horizon.
