At the heart of Duncan's tales are characters undergoing the complex and violent process of transformation, with results both painful and wondrous. Equally affecting are his nonfiction reminiscences, the "river teeth" of the title. He likens his memories to the remains of old-growth trees that fall into Northwestern rivers and are sculpted by time and water. These experiences--shaped by his own river of time--are related with the art and grace of a master storyteller. In River Teeth, a uniquely gifted American writer blends two forms, taking us into the rivers of truth and make-believe, and all that lies in between.
