She's a grumpy security expert...Reese doesn't do relationships. Especially not with tall, sexy men with golden retriever energy. Nope, she prefers her men brooding and silent-with no strings attached. So when she hooks up with her gorgeous coworker after their friends' wedding, she does what any sane woman would do. She runs.He's a sunshine badass...Unfortunately for her, they've got to go undercover at a couples' retreat which means one room, one bed, and a simmering heat neither of them can deny. Constantine-aka Cash to his friends-has been burned before because of his wealth. But Reese wants nothing to do with his money, which only intrigues him even more.

Something that proves more difficult when people around them start dying.
