He'd protect her from any threat... But what if the biggest threat is him?

Doctor Anne Griffin is back in Oak Creek, Wyoming only because she has no other options. Here, she was always the shy, stuttering girl, invisible to everyone.

Except Zac Mackay. The very reason she left in the first place.

Zac's years in Special Forces taught him survival skills, and he's created a company--Linear Tactical--to teach those skills to others, so they never have to live in fear.

Then why is Annie, the last person he'd ever want to hurt, afraid of him?

Zac's determined to wipe the fear from the eyes of the woman who has never been far from his mind. And fix the mistakes--his mistakes--that put that look there in the first place.

But a predator has set his sights on Annie. And now survival skills will become much more than lessons...
