Long after Bramblestar's era, the clans of the lake, polarized and crumbling, are forced to come together by a great reckoning. In the chaos, the lives of four cats are irrevocably tangled together when each of their individual goals have consequences for the others. In WindClan, Wasplight mourns a friend even as he finds himself falling in love with someone whom he shouldn't. In RiverClan, Eaglestorm is pushed into a position of power that has her butting heads with cats on all sides and wary of who she can trust. In ThunderClan, Snowpaw's ambition gets them stuck in a double-bind with their sister's life on the line. In ShadowClan, Magpiemoon cannot die.
