Ohkwa'ri and his twin sister, Otsi:stia, 11, are late-15th century Mohawks living in what would become New York State. Both are exemplary young people: He is brave, kind, and respectful of his elders, and she is gentle and wise beyond her years. One day Ohkwa'ri hears an older youth, Grabber, and his cronies planning to raid a nearby Abenaki village, in violation of the Great League of Peace to which all the Iroquois Nations have been committed for decades. When Ohkwa'ri reports what he has heard to the tribal elders he makes a deadly enemy of Grabber. Grabber's opportunity for revenge comes when the entire tribe gathers for the great game of Tekwaarathon (later, lacrosse). Ohkwa'ri knows that he will be in great danger during the long day of play and will have to use all his wits and skills to save himself and his honor. Bruchac (Between Earth and Sky, p. 445, etc.) saturates his novel with suspense, generating an exciting story that also offers an in-depth look at Native American life centuries ago. The book also offers excellent insights into the powerful role of women in what most readers will presume was a male-dominated society. Thoroughly researched; beautifully written. (Fiction. 8- 11)
