At the end of Mark Twain's Huckleberry Finn, on the eve of the Civil War, Huck and Tom Sawyer decide to escape "sivilization" and "light out for the Territory." In Robert Coover's Huck Out West, also "wrote by Huck," the boys do just that, riding for the famous but short-lived Pony Express, then working as scouts for both sides in the war.
They are suddenly separated when Tom decides he'd rather own civilization than leave it, returning east with his new wife, Becky Thatcher, to learn the law from her father. Huck, abandoned and "dreadful lonely," hires himself out to "whosoever." He rides shotgun on coaches, wrangles horses on a Chisholm Trail cattle drive, joins a gang of bandits, guides wagon trains, gets dragged into U.S. Army massacres, and eventually finds himself in the Black Hills just ahead of the 1876 Gold Rush. In the course of his adventures, he reunites with old friends and faces some hard truths and even harder choices.
