Troubled Graves by Christy Barritt

Some things are best left buried . . .

Gunner Mathias is trying to come to terms with a life-changing injury that ended his career as a Navy SEAL. While at a retreat at Hope House on Lantern Beach, he hopes to heal so he can move forward with his life. The last thing he expects is to run into a woman he once rescued.
Noelle Purdy wants to use her expertise as a scientist for the betterment of others. Someone sinister has other plans. When a masked man attempts to abduct her, a stranger jumps in to help . . . only he’s not a stranger. He’s a hero from her past, someone she’s never forgotten.
Gunner and Noelle didn’t think they’d ever see each other again. But now long-dormant secrets have been resurrected, and Noelle is the only one who can stop the grave danger soon to be unleashed. Can Gunner and Noelle overcome old wounds in order to protect everything they love? Or will trouble from their past destroy them both first?
