Book Three of Lloyd's Riverboat Trilogy This novel of the dangerous Missouri River can be enjoyed as a stand alone novel. For readers who enjoyed Book One and Book Two of Lloyd's trilogy, The Captains completes the riverboat series as Caleb, Harvey and Storm, the Indian woman rescued form the river, experience the rigors of the Civil War and its aftermath. Together, the two men take on river pirates, Indians and Confederate Guerillas, while Storm seeks to return to her heritage, the Indian life in the Rocky Mountains. Fort Benton becomes the head of navigation on the Missouri River, "the world's innermost port," as the demand for transportation of passengers and goods up to the Montana goldfields forces the captains to seek ever shallower draft boats to take on the "Big Muddy" which is "too thin to walk on, too thick to drink."
