Saving Faithless Creek — Andrew Grey

Blair Montague is sent to Newton, Montana, to purchase a ranch and some land for his father. It's a trip he doesn't want to make. But his father paid for his college education in exchange for Blair working for him in his casinos, so Blair has no choice. When he finds out he'll be dealing with Royal Masters, the man who bullied him in high school, he is shocked. Then Blair is surprised when he finds that Royal's time in the Marines has changed him to the point where Blair could be attracted to him… if he's willing to take that chance.

Royal's life hasn't been a bed of roses. He saw combat in the military that left him scarred, and not just on the outside. When he inherits his father's ranch, he discovers his father wasn't a good manager and the ranch is in trouble. The sale of land would put them back on good footing, but he is suspicious of Blair's father's motives, and with good reason. The attraction between them is hard for either to ignore, but it could all evaporate once the land deal is sealed.
