The Widowmaker Reborn — Mike Resnick

Jefferson Nighthawk was the consummate killing machine, the most feared bounty hunter in the galaxy--the Widowmaker. For over a century he has been frozen, awaiting the cure for a deadly disease. But frozen bodies can be cloned, and the Widowmaker can kill again....

The first cloned Nighthawk had the Widowmaker's talents and instincts, but none of his experience with human and alien nature--and for that, he paid with his life. Now a second clone has been created, with his namesake's lifetime of memories, hard-won knowledge, and basic rule for survival: Trust no one.

His mission is to save the daughter of a corrupt politician and kill the rebel leader who holds her captive. But the rescued beauty offers him a better deal: turn against his employer and steal his ill-gotten fortune. The odds against success are a million to one. But for the Widowmaker, the odds--and the price--are right.
