Discover the origins of the warrior Clans in the second book of this thrilling prequel arc from mega-bestselling author Erin Hunter. The Dawn of the Clans series takes readers back to the earliest days of the Clans, when the cats first settled in the forest and began to forge the Warrior code. The mountain cats from the Tribe of Rushing Water followed the Sun Trail to a new territory, convinced that in a land with more prey, their lives would be free from strife. But while no cat has gone hungry, tensions are rising. The once firmly united group has split in two-and a young cat named Thunder is caught in the middle.
