Moons have passed since six cats set out on a journey to save their Clans. Meanwhile, back in the forest, Firestar and Leafpaw watch ThunderClan's world crumbling around them. Will the questing cats make it back in time, or will they be too late?

"The warrior cat Clans have enjoyed many moons of peace and prosperity--but a dark season approaches, and those days will soon be over. Guided by a mysterious vision, the young apprentice Alderpaw of ThunderClan must go on a dangerous journey...a journey that may be the Clans' only hope." --

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 ThunderClan's newest member are hampered by her treacherous mother.
