Book Reviews
(Books prior to the internet have few, if any, mainstream press reviews online. See Amazon and Barnes & Noble for helpful customer reviews.)

Weaves a dense web of subplots involving secondary characters and out-of-the-way places, with the idea of using the form of a long old-fashioned realistic novel to create an accurate picture of life on the American frontier.... The Great Cowboy Novel.
Nicholas Lemann - New York Times

If you only read one western novel in your life, read Lonesome Dove.
