A modern-day Huck Finn, Buck casts off down the river accompanied by an eccentric crew of daring shipmates. Over the course of his voyage, Buck steers his fragile wooden craft through narrow channels dominated by massive cargo barges, rescues his first mate gone overboard, sails blindly through fog, clashes with overzealous period reenactors, and much more. In addition, he charts his own geographical and emotional journey while also delivering a richly satisfying work of history that brings to life a lost era. As Buck points out, the inland rivers of the Ohio and Mississippi Valleys were in fact America's first western frontier.
