Into the Sun

The sun is disappearing, each day it gets smaller. The medicine cat of Valleyclan, Spottedriver, received a prophecy, "One cat, the heir of a villain, will once again prove his heroism, before the sky turns red"
Longstep, the kit of the most hated warriors daughter, is ending his apprentice ship to become a warrior when Spottedriver, drags him into her den, telling him the prophecy, and now the weight of the world sits on his shoulders.
