A Moment in Time by Josie Kerr

Ben “Gunny” Anderson spent twenty years in the United States Marine Corps, watching the enemy through the scope of a long gun, waiting for the right moment to snuff out their lives. Now he’s retired and while he figures out what he wants to do with the rest of his life, he’s working with some former teammates, renovating properties.
After a scandal ruins her professional and personal life, Lindsay Beaujardin is looking for a brand new start and a move from Louisville to Atlanta is the perfect way to begin again.
A three-day fling between Gunny and Lindsay turns into the shock of a lifetime when they unexpectedly cross paths again. All it takes is a moment in time to change the course of fate and Gunny and Lindsey are about to find out just how true that is.
