Bound Like Grass: A Memoir from the Western High Plains. (Jamie Ford's novel, Hotel on the Corner of Bitter and Sweet, won the 2009 award.)
Bound Like Grass is an engaging story that encompasses three generations: the idealistic homesteader grandparents, the hard-working parents, and the children who grew up, moved away and never returned.
Also nominated for the 2010 award were Everything, by Kevin Canty (the only fiction book nominated), Goodbye Wifes and Daughters, by Susan Resnick, The Last Stand: Custer, Sitting Bull, and the Battle of the Little Bighorn by Nathaniel Philbrick, and Visions of the Big Sky: Painting and Photographing the Northern Rocky Mountain West by Dan Flores.
