Plowed (Blue Collar Bad Boys #7)
Brill Harper

The fields are fallow, my house is falling down around my nearly catatonic father, and my ex-girlfriend is somebody else's wife now. But I'm not giving up. I'll replant the crops, fix the house, and find a wife. Not in that order, because a man has needs, and mine have been denied too long.
The quirky, extra-curvy waitress at the diner could use someone looking out for her, and I need a favor in return. Starting with a baby.
This farmer is about to take a wife.
I hope she's ready for me.
Author's Well, there's a lot of plowing and seeding on the farm, yeah? Prepare yourself accordingly.
