The day before Bluefur gives up her kits, she changes her mind and decides to raise them as her own. But as time goes on and Thistleclaw becomes leader, Bluefur realizes that her choice may have sent ThunderClan on the path to its downfall. Major Character Death Warning!!!

While RyeClan and ShallowClan are both strong clans in their own right, their bitter rivalry runs acrid through the river and has torn apart generations. As adversity approaches from all sides, the two clans must struggle through, whether apart or together, and decide their fate.

The cats of the mountain have only one enemy: the wolf pack. The wolves linger on the edges of their territory, and their howls echo through the pine forests each night after the sun goes down. Generations ago, they were revered as gods; a single bite could kill a cat and their paws shook the earth when they hunted. Now, they are feared, both in legends and in reality. Many have fallen to their jaws. They are savages, unpredictable, irrational, unnatural. The greatest punishment to be inflicted on a cat is to be forced into their skin. The elders have a fairytale, passed down from mother to kit for countless years. It tells of a cat who was cursed by his ancestors to be trapped in the body of a wolf each winter night. The sickness took hold in his body and transformed him into something monstrous. A murderer. A cat-eater. It's a kit's tale with a clear moral: Stay away from the wolves. But what happens when the line between reality and fantasy blurs? What happens when the darkest kit's tale the elders have ever invented becomes real?
