The Domes: Battle Foxes

In their harsh world, animal ancestors of all sorts created "The Domes". In each dome, there is a specific animal. The Domes: Battle Foxes, focuses on the fox dome, where four special cubs are born: Soft, Thorn, Grace, and Apple. Their mother, the healer of the skulk, recieves a prediction from their fox ancestors up above. Something evil is lurking within one of the cubs, and only the other three can save the skulk. Question is, will they betray their own sibling just to save their skulk?
(This is not a fanfiction btw. I tried to keep it as original as possible, but to me its really close to warrior cats or foxcraft. What do you think? Also the cover does not belong to me. It belongs to its rightful owner)
