It’s a Wonderful Date by Sophia Summers

Love is the last thing on Sarah’s mind until she meets the small town doctor: single, handsome, and he lives across the street.
The doctor, however, has given up on ever finding love, not in this small town. As the only member of his practice, he has no time to himself when he works to be everything for everybody. But a beautiful new woman in his neighborhood keeps catching his eye.
When everything falls apart and he can’t save a much-loved patient, he wonders how much good he really is for his town.
Sarah becomes the angel of his Christmas wishes, who shows him just how much he means to not just her, but their small town and everyone in it.
