My One and Only by Terri Osburn
As far as Dr. Haleigh Rae Mitchner is concerned, Cooper Ridgeway is more suited to a superhero cape than mechanic's overalls. It's just like Ardent Springs's most upstanding resident to rescue a pregnant, homeless teenager and bring her to Haleigh's delivery room. When they team up to help the new mother and baby, Haleigh is determined not to cross the line with Cooper. Not only is he her best friend's brother, he's a guy who deserves more than Haleigh's checkered past could ever offer. At first glance, Haleigh is no longer the girl Cooper pined for in school. The sleek, professional OB-GYN seems more out of reach than ever for this small-town mechanic. But the more time he spends with the complicated woman, the more he wants her. Who better than Cooper to prove to her that nothing is beyond fixing? Especially in Ardent Springs, a town that's tailor-made for second chances.
