Hard to Kill — Jon Mills

Jack Winchester is a drifter. A ghost to those who pursue him and a danger to those who confront him. Once a notorious hitman for a New Jersey crime family, Jack is now a fugitive trying to right his wrongs. Wanted by the FBI and hunted by one of the Sicilian Mafia's top assassins, he travels to New Orleans to reconnect with an old flame. But things aren't what they seem. Not only must he cross paths with a ruthless drug lord just as Hurricane Danielle makes landfall, but he's about to discover that he may be the only one that can save his ex and daughter.
