Sweetwater Gap by Denise Hunter

When Josephine's family insists she come home to help with the harvest, the timing works. But her return isn't simple benevolence-she plans to persuade the family to sell the failing orchard.

The new manager's presence is making it difficult. Grady MacKenzie takes an immediate disliking to Josephine and becomes outright cantankerous when she tries talking her family into selling. As she and Grady work side by side in the orchard, she begins to appreciate his devotion and quiet faith. She senses a vulnerability in him that makes her want to delve deeper, but there's no point letting her heart have its way-he's tied to the orchard, and she could never stay there.
