My Bodyguard — Dana Marton

Bodyguard Reese Moretti had been involved in missions all over the globe, so tracking down an international criminal should have come naturally. But partnering up with a woman as frustratingly closed-off and downright sexy as Samantha Hanley made it the most challenging job he'd ever taken on. To make matters worse, they were instructed to act like a couple and ferret out the truth behind an ingenious--and deadly--plot. Reese had made a promise to the FBI and completing his assignment was all that mattered. But touching Sam day in, day out and pretending it meant nothing, was never part of the dossier.
