The Broken Land: A People of the Longhouse Novel (North America's Forgotten Past)

Twelve summers after the events of The People of the Longhouse and The Dawn Country, the Iroquois nations remain locked in bitter warfare. Atotarho, the cannibal-sorcerer who leads the People of the Hills, schemes to set into motion a cataclysmic battle that threatens to destroy the Iroquoian world. His warriors spread fear and death wherever they go, taking captives and burning villages to the ground.

Only five people are brave enough to challenge Atotarho. Odion, Wrass, Tutelo, Baji, and Zateri, kidnapped as children and sold into slavery, are now grown, and they have forged a desperate alliance that just might be strong enough to stop the madman. 

Odion, now a disgraced warrior known as Dekanawida or Sky Messenger, must convince his people that his visions of a great darkness will mean total destruction for all. His friend Wrass, who has become War Chief Hiyawento, and a powerful clan matron, Jigonsasch, are his only hope. They must find a way to bring five warring nations together.
