When it comes to murder, Serena and Lawton couldn't be more different. There's only one thing they have in common-they're both contract killers. Serena's a clever, Manhattan darling with a penchant for poison-tipped manicures. Lawton is a reckless, down-and-dirty cowboy who isn't afraid to make a mess, as long as he gets the job done. They've despised each other for years, ever since that one fatal night...

But when they're hired for the same job in Wyoming, they quickly realize they'll have to put their differences aside if they want to get it over with. The only catch? They have to play the part of an oh-so-happily married couple. As if that isn't hard enough, things get even messier when they start questioning their targets, thinking this might not be the job they initially signed up for. Did they just stumble into a dangerous trap? And more importantly, will they kill off any chance at something real before they can make it out alive?
