Come a Little Closer by Kait Nolan

Griffin Powell has avoided his hometown since he left it in the rearview years ago. But the former Marine understands duty and promises, and that means dragging himself back home as part of his brother's wedding party. Which gets him thinking about a promise he made to a woman, after the best night of his life. When she, too, shows up as part of the wedding, it feels like a sign. Always a bridesmaid, professor Samantha Ferguson is dreading this bachelorette weekend. She’s the one of the lone single ladies, and the matron of honor is her high school nemesis. Sam figures she can suck it up and deal, until she comes face-to-face with the big, sexy ginger mistake from her past. Can this trip home get any worse? Turns out it can. Not only are she and Griff paired up for all the bridal party bonding activities, forcing her to relive high school hell, but Sam's best friend goes missing. When no one takes her concerns seriously, she starts a search herself--and ends up with an unwanted bodyguard whose very presence reminds her of a hot Vegas night she’s tried hard to forget.
