A slight story relates an Ojibway boy, Half Sky's twelfth year and serves as a vehicle to describe Indian life in the days before the white man. Approaching manhood, Half Sky's life is centered around the pilgrimage he must make to Dreamer's Rock, there to stay and fast until the vision of his animal spirit comes to him, and, further to qualify himself for the event, he is able to warn his tribe of an impending Iroquois attack. Though a capture occurs, the Ojibway warriors return unharmed. All this against the backdrop of seasonal and daily customs, makes an adequate if familiarly patterned book.
