Plot
The Sun Trail begins with a group of cats known as the Tribe of Rushing Water, led by Stoneteller, starving due to lack of food in their mountain home. Stoneteller receives a vision in which she is told that there is more prey if one follows the rising Sun. When one of the Tribe's kits dies of hunger, a group of Tribe cats decides to follow the "Sun trail" as described to Stoneteller in her vision, in search of a solution to their situation. However, a kit named Jagged Peak sneaks out of the Tribe's cave to catch up to his older brother, Clear Sky, who is in the group of Tribe cats who have left. This prompts their mother to ask their other brother, Gray Wing, to follow Jagged Peak. Gray Wing reluctantly agrees, saving Jagged Peak from an eagle attack before they catch up to Clear Sky's group.

During a nighttime stop on their journey, the cats are attacked by a trio of eagles who carry away Clear Sky's mate, Bright Stream, when she saves Gray Wing from the eagles. Bright Stream kills the eagle carrying her but falls to her death. In the aftermath, a rift forms between Clear Sky and Gray Wing because Gray Wing believes that Clear Sky blames him for Bright Stream's death. However, it is later revealed by Clear Sky that he blames himself for Bright Stream's death; the brothers reconcile after Gray Wing suggests that the death was simply a terrible accident of nobody's fault. Shortly after Bright Stream's death, the journeying cats leave their mountain territory and enter unfamiliar terrain. Their journey is continued in the sequel, Thunder Rising.
