It has been a long time since the conclusion of the second Great Battle. The threat of Splashheart and the Dark Forest has faded after Crazystar's success. Although the legendary gray-furred she-cat has long since been with StarClan, her legacy continues on within all of the Clans, not just ThunderClan. On the opposite side of the lake, one of the kits of Salmonstar, Crazystar's friend in RiverClan, has just risen to the title of leader after the tragic death of Tawnystar. Although there has been a long stretch of peaceful moons, it appears that the days of Pebblestar's leadership may be darkened by an ominous prophecy: Horses territory will part the great river in two. After a tough choice, Pebblestar turns to his sister, Minnowstream, and asks her travel far from the lake on a dangerous adventure. As Minnowstream sets out as the leader of a long journey, she begins to wonder if she can truly handle the responsibilities of this journey and overcome the challenges she must face to reach the destiny StarClan has laid out for her.
