New Prophecy

The second series, Warriors: The New Prophecy, was released from 2005 to 2006, and contains six books: Midnight, Moonrise, Dawn, Starlight, Twilight, and Sunset. This plot follows six cats: Brambleclaw, Tawnypelt, Crowpaw (later Crowfeather), and Feathertail, who are sent on a mission by StarClan to the sun-drown place (ocean), with Feathertail's brother, Stormfur and a ThunderClan apprentice, Squirrelpaw (later Squirrelflight), accompanying them. There, a badger named Midnight tells the six cats that Twolegs (humans) will be making a Thunderpath (a road) that cuts across the Clans' territories, forcing the Clans to leave.
On the way back to the forest, the traveling cats meets a group of cats called the Tribe of Rushing Water, who are being terrorized by a mountain lion called Sharptooth. The Clan cats stay with the Tribe, but later run away. However, they then go back to help defeat Sharptooth. After luring Sharptooth into the cave where the Tribe lives, the cats attempt to fight him off. Feathertail jumps onto a rock spike on the roof of the cave and plummets to the floor with it, falling on Sharptooth and crushing him, sacrificing her life to save the Tribe.
In Starlight and Twilight, Leafpool and Crowfeather fall in love with each other. Crowfeather admits to Leafpool that he loves her when he saves her from falling off a cliff, in a situation similar to Feathertail's death. However, the warrior code says that she as a medicine cat cannot have a mate. They eventually abscond, but return because Midnight warns them that a large group of badgers were attacking ThunderClan. Upon returning, they find that a badger has killed Cinderpelt, the ThunderClan medicine cat, while she was helping Sorreltail give birth. Shortly after, Leafpool discovers that Cinderpelt in reincarnated as Cinderkit one of Sorreltail's kits, though Cinderkit does not know this herself. Cinderkit follows the path of a warrior in her new life, and gets her warrior name, Cinderheart.
The series then centers around the prophecy "before there is peace, blood will spill blood, and the lake will run red". Hawkfrost and Brambleclaw have been meeting with their father Tigerstar in dreams, in which he is teaching them how to become Clan leader by force. Hawkfrost follows Tigerstar every step of the way, but Brambleclaw is split between loyalty to his leader, and his own ambition. Firestar appoints Brambleclaw deputy after finally accepting the possibility that Graystripe might never return. The series reaches its climax when Hawkfrost traps Firestar in a fox trap, and tells Brambleclaw to kill him. Brambleclaw decides that he does not want to become leader by force, and refuses to kill Firestar; instead, he frees him from the trap. Hawkfrost attacks Brambleclaw, but Brambleclaw kills Hawkfrost with the stick he used to free Firestar.
