Rugged Guard by Jason Collins

DEREK:

Parker was supposed to be off-limits.
After the military, I’ve never wanted to put down roots. My work as a bodyguard sends me all over the world, so protecting a quiet B&B should be a vacation. Guarding three brothers seems easy—but Parker complicates things.
I wasn’t prepared for romance, much less with a man, but Parker makes me want to break all the rules. I can’t stay away from him, and I don’t want to. A fire brings us together, and once we have a taste of each other we can’t slow down.
But I’m not the kind of guy who can stay in one place. Now that I’ve been with Parker, my heart’s torn between the need to keep moving and the urge to be his protector.
It isn’t easy guarding a man you can’t resist.

PARKER:

I’m in danger, and all I can think about is Derek.
My bed and breakfast needs protection, so my brothers hired a bodyguard. Derek is the hottest man I’ve ever seen, and he’s the only thing shielding me from threats. After my dad’s unexpected death, I’ve been feeling vulnerable, but it gets even worse when I discover a menacing letter that may be tied to what happened to him.
I can’t keep my eyes off Derek, but he’s either too professional or too straight to notice. I try to fight my feelings until he saves me from a fire, but the heat between us turns our relationship less than professional.
Once we find who was threatening my dad, I won’t need a bodyguard, but I might still need Derek. He’s more than just protection now—he’s the man I can’t resist.
He can’t fall for a client, but I might not be able to help it.

This is the first book in the Mountain Men series. It can be enjoyed as a standalone with no cliffhanger.
