"When the blood covers the moon, peace will drown in the ashes of war." The traveling cats have returned to the mountains with an entire new Clan, StarClan's mission has been completed but there is darkness shadowing all five Clans as they attempt to establish stability in their lives. In AshClan, Slatepaws's sharp attitude and ego is finally catching up to him and he is forced to go through a very harsh wakeup call which forces him to change his perspective, despite his reluctance. In MountainClan, Mountainstar's life has changed completely in only two moons and she struggles to be a good leader while trying to build confidence, pride and respect within her Clan of rouges, kittypets and loners. In MoonClan, Leopardpaw is happy to return to her normal life as a warrior but tensions and unrest are brewing a storm within the normal peaceful Clan and as an apprentice, she fears there is nothing she can do to stop it. In SunClan, Blossompaw is fighting a constant battle with her self-worth and second guessing all of her skills, always pushing herself to the brink of exhaustion and still never feeling good enough, just desperately trying to be a good SunClan warrior. Owlpaw has finally set her paws on the path of a medicine cat, but despite her best efforts she still feels out of place and in the way, and to make things worse she is faced with another mission from StarClan, and if she fails this one; death and violence could consume all five Clans.

Icekit was a white fluffy kitten with ice blue eyes. She was born in the Fishers' Paws clan, where only sleek furred cats were allowed. Her mother, Wisptail, took care of her in careful hiding, so careful she would only leave her den to wait outside for a cat to bring the food. Only one day, she went hunting with her friend, leaving Icepaw, who was newly learnered, sleeping in the den. Only a learner went in, curious for a friend. Mosspaw found out about the 'coded' Icepaw and ran screaming to Wavestar, who was furious. When Wisptail came home, it was too late- Icepaw had run away.
