Veteran writer, rancher and environmentalist O'Brien (The Rites of Autumn) deftly chronicles his decision to restore buffalo to his 1,000-plus-acre South Dakota ranch for the first time in more than a century. Some 20 years before this life-changing decision, O'Brien was drawn by visions of "grass swaying in the wind to infinity and a sky that takes up half the world" to purchase the Broken Heart ranch. Despite his passion for the Great Plains and "the wild things that share the place," most of the intervening years were devoted to making a going concern of his cattle operation. Then, in January 1998, a recently divorced O'Brien sold his cows and purchased 13 buffalo "runts" from a neighbor. From this initial "crew of ragamuffins" he eventually built a herd of 100, assuming considerable financial risk to acquire the animals and construct eight miles of five-foot-high, barbed wire buffalo fence around his property. O'Brien reflects on how the symbiotic relationship between the animals and the prairie helped return his land to health. In contrast, he documents the difficulties of raising cattle, "sort of ungulate tourist[s]" ill-suited to the harsh plains landscape. Relying on his natural storytelling ability and a gift for character development, O'Brien interweaves his own experiences with a history of the region and engaging portraits of his neighbors. The result is a moving story of one man's love for a place and his desire to "make the land whole again." (Sept.)
