Break My Fall by Lynn H. Blackburn

Dr. Meredith Quinn always planned to return to Gossamer Falls to practice dentistry. Now that she’s back home, she’s made it a point to offer clinics to children and adults in nearby underserved areas. Unfortunately, those same areas are known to harbor drug traffickers, and Police Chief Grayson Ward suspects that local law enforcement is looking the other way.
After too many losses, Grayson has closed off his heart. But when Meredith enters his life, his walls crumble, and he’s left exposed and vulnerable. To keep her alive, he must keep her close, but that makes it impossible for him to retreat and rebuild. Will she be the one who finally helps him emerge from isolation? Or will this force of nature leave him shattered?
