Walnut is an Native American boy who lives in America in the 16th century. He is growing toward manhood but struggles with many of the basic tasks of Native American life because his eyesight isn't that good. He can't see to shoot an arrow, but when a friend loses a bone needle, Walnut can see its location in his mind's eye quite clearly, and he knows precisely where the bone needle can be found. His gift proves useful as he is asked to take another Native American back on a journey to solve the mystery of a tragic time. 128 pages
