Countless seasons ago, in an effort to increase inter-Clan unity, the Clans implemented the Rotation, a unique training program in which apprentices train in all four Clans before choosing which one they wanted to call home. And, for the most part, it's worked-until a dangerous ShadowClan warrior named Tanglespirit took advantage of the Clans' more relaxed attitudes to seize power. A terrible and bloody war followed, and after many moons of fighting, Tanglespirit and his supporters were defeated and exiled from the Clans.
Young Lightningpaw of ThunderClan, left orphaned after the war, can't wait to start his Rotation and become a great warrior. Accompanied by his friends Oakpaw and Otterpaw, he sets off for ShadowClan, where he meets Shadowpaw, son of the ShadowClan deputy. But then rumours of Tanglespirit's return start circulating, and Lightningpaw realizes that the peace he's always taken for granted is but an illusion that threatens to come crashing down.
Shadowpaw of ShadowClan also wants to become a great warrior-so that he can help Tanglespirit return to power and save his Clan. He couldn't care less about learning from the other Clans, and sets off on his Rotation determined to make the other Clans fear ShadowClan again.
But Tanglespirit is three times as clever as any cat-except perhaps Foxstar of ThunderClan-thinks he is, and as his tangled web of deceit pulls Lightningpaw and Shadowpaw closer together, both apprentices will have to choose where their loyalties lie if they want any chance of saving the Clans they call home.
