Dark River

Dark River is a river of trials that the children of Squirrel and Blackberry, grandchildren of the great leader Firestar - Sparrowpaw, Ashfoot, and Lionpaw - must cross.
Lionpaw forms a dangerous friendship - not just one! - and must keep it strictly secret;

Sparrowpaw explores the limits of his strength and magical connection with the StarClan cats; Ashfoot learns something that could prevent the looming war, and acts at her own risk.
The growing contradictions threaten to disrupt the fragile balance and wash away the world of the warrior cats.
