New Orleans, 1891: Lee Christmas gets drunk and falls asleep at the throttle of his locomotive, plowing straight into an oncoming train. Blacklisted from the railroad and his marriage in tatters, he flees New Orleans on a steamer bound for the tropics.

In Honduras, he begins a quiet new life. But trouble has a way of finding Christmas. With unrest sweeping the countryside, he's kidnapped by bandits. Soon, he finds himself taking sides in an all-out civil war--as leader of the rebellion.

MERCENARY is the thrilling story of the USA's most famous soldier of fortune: the hard-drinking drifter who changed the fate of a nation.
