Hard to Hold by Jami Alden

Growing up on the Lazy Creek Guest Ranch, Paulina Osborn knew that in order to be taken seriously in the family business, she needed to work harder than anyone else and be above reproach (or something like that). Determined to maintain the professional image she’s spent years establishing, she’s learned to keep everyone in the dark about her dating life. When she indulges in one night with a hot stranger, she’s not worried about keeping it a secret. After all, it was just a meaningless fling in a town fifty miles away, with someone she’ll never see again. But it’s a disaster waiting to happen when her sexy stranger waltzes into her office and introduces himself as their new summer hire.
After a twenty year career as an Army Ranger, Seth “Mack” MacKinnon is finally ready to settle down and put down roots. A job at his step-father’s company will provide the kind of income and stability that can support his future family, even if it is a far cry from his childhood dream of taking over his grandfather’s farm in Montana,. But a summer job working at the Lazy Creek Guest Ranch in Big Timber, Montana is the perfect way to fill his last free months before he moves on to the next phase of his life. It’s even more perfect when he discovers his boss is none other than the gorgeous woman he spent one unforgettable night with. What could be better than a hot summer fling before he settles down for good?
Paulina is determined to keep things professional, and while Mack is willing to keep his distance, too soon the chemistry sizzling between them explodes. Before long, Paulina and Mack are indulging in a steamy, secret affair that they both know won’t last past summer.
But as the months pass, Paulina finds herself wishing that Mack’s future could include her. And Mack’s growing feelings for Paulina threaten to derail all of his carefully laid plans.
