Heart of Texas Volume 2: Caroline's Child / Dr. Texas (Heart of Texas, Vol. #2)
Debbie Macomber

Dr. Texas.
They call her Dr. Texas. She's Jane Dickinson, a newly graduated physician from California who's working at the Promise clinic-but just for a couple of years. They call "him" Mr. Grouch.
Cal Patterson was left at the altar by his out-of-state fiancee, and he's not over it yet. Too bad Jane reminds him so much of the woman he's trying to forget.
