One Shot by DL Jackson

One shot, one kill—The United States Army Sniper Creed.

For centuries, brave men have served America, taking out dangerous targets before they can attack. But women are about to shake things up. When the daughter of a senator, Sergeant Paige Davis is offered an opportunity to follow in her father’s bootsteps as an army sniper, she unknowingly draws the attention of an organization bent on bringing down the freedoms of the American people.
Little does Paige know, her father’s political agenda has put a target on her back, and he’s hired Omega to keep her alive. If the pilot program fails, it could be decades before women get the chance to enter combat arms again.
Enter Staff Sergeant Nolan Stone, aka, the babysitter. He’s a Marine and has been reactivated by the Department of Defense to secretly watch Davis’ back while she undergoes controversial sniper training he’s very much against. Women don’t belong in combat arms as far as he’s concerned, and the program is sure to fail, but not because the senator’s daughter got killed. Not on his watch.
When he meets Paige face-to-face, Nolan realizes he might have to change his way of thinking. The strong-willed Davis is more than his match on a battlefield and in the bedroom, and if he’s not careful, she might bring this MARSOC marine to his knees.

He’s got one shot to keep her alive and win her heart. If he fails, he’s going down with her.
