"Bluestar's Prophecy" follows the life of Bluestar, the leader of ThunderClan. The book starts with a prologue that recounts Bluestar's death in "A Dangerous Path". The book then goes back to Bluestar's childhood, during which Goosefeather, the Clan's medicine cat, receives a prophecy about Bluepaw being a fire that will blaze through the forest, but who will be destroyed by water. A few moons later, Bluepaw's mother, Moonflower, is killed in a battle.
