The five Clans have been thriving since Firestar died decades ago during the Great Battle. Cats have risen to lead the Clans for generations after his death.
Cliffkit is taken in by ThunderClan and raised with his foster siblings and is eager to prove himself ready to become a warrior. But when tragedy strikes in the Clans, it is up to Cliffkit to find the cats who are responsible for the murders of his friends, family, and Clanmates.
