Twelve-year-old Okwaho's life has suddenly changed. While he and his best friend are out hunting, his friend is kidnapped by men from a neighboring tribal nation, and Okwaho barely escapes. Everyone in his village fears more raids and killings: The Five Nations of the Iroquois have been at war with one another for far too long, and no one can remember what it was like to live in peace.

Okwaho is so angry that he wants to seek revenge for his friend, but before he can retaliate, a visitor with a message of peace comes to him in the woods. The Peacemaker shares his lesson tales--stories that make Okwaho believe that this man can convince the leaders of the five fighting nations to set down their weapons. So many others agree with him. Can all of them come together to form the Iroquois Great League of Peace?
