Jim Harrison's The Theory and Practice of Rivers returns to print as a celebratory, stand-alone volume. In her heartfelt and powerful introduction, Rebecca Solnit calls this collection both an elegy, inspired by the death of Harrison's teenage niece, and a "loose memoir" teeming with thoughts and images that leap intuitively across subjects, recalling myriad experiences, places, and encounters. A handwritten draft of the title poem, retrieved from Harrison's extensive literary archive, provides a rare and intimate window into his surging creative process. As Outside magazine puts it, The Theory and Practice of Rivers is filled with "moving water, the search for consolation and meaning in the sublime rightness of wild landscape." This contemporary classic speaks to the rivers and cascades in all of us, the ceaseless motion by which our lives are determined.
