When struggling riverboat captain Abner Marsh receives an offer of partnership from a wealthy aristocrat, he suspects something’s amiss. But when he meets the hauntingly pale, steely-eyed Joshua York, he is certain. For York doesn’t care that the icy winter of 1857 has wiped out all but one of Marsh’s dilapidated fleet. Nor does he care that he won’t earn back his investment in a decade. York has his own reasons for wanting to traverse the powerful Mississippi. And they are to be none of Marsh’s concern—no matter how bizarre, arbitrary, or capricious his actions may prove.
