While Frostpaw takes refuge in ShadowClan as Splashtail seizes control of her home, Nightheart returns to ThunderClan and to a complicated reunion with his mate Sunbeam whose efforts to fit in as ThunderClans newest member are hampered by her treacherous mother.Frostpaw has returned to the lake just in time to reveal all she knows at the Gathering--but the Clans are reluctant to believe an apprentice whos already admitted to lying about her visions in the past, and she is forced to take refuge in ShadowClan as Splashtail seizes control of her home. While the other Clan leaders debate whether to interfere any further in RiverClan affairs, Nightheart has his paws full teaching Clan ways to the two park cats who followed him home, and Sunbeams efforts to fit in as the newest member of ThunderClan are hampered by her concerns for her mother, who is paying for her treachery with exile and illness. As Berryhearts schemes take an alarming new turn--and Splashtails ambitions turn toward violence--a few cats efforts may not be enough to preserve the peace.
