Trigger Happy by Meredith Trapp

From the acclaimed author of the western romance Homebound, two rival killers with hundreds of missions under their belts face their hardest assignment yet: marriage.

For these rivals, the chemistry is lethal.

Sabrina and Lawton go together as well as Dom Perignon and Frito pie. They have nothing in common—except for the fact that they unalive people for a living. Sabrina’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 get the pigs involved in clean-up duty. They despise each other, and not just because of what happened two years ago…

When they’re hired for the same job in cozy, postcard-perfect Wyoming, they quickly realize they’ll have to stop tossing out death threats if they want to get it done successfully. There’s only one problem...They have to pose as an oh-so-happily married couple to get close to their targets, which means strolling through pumpkin patches and smiling on horseback rides—all while pretending they’re not fantasizing about what the other would look like in a coffin. Things get even messier when they start wondering if they’ve walked into a dangerous trap. And, more importantly, will they kill off any chance at something real before they make it out alive?
