Can anyone help me with the name of a book I read ages ago. For the life of me I can't remember it's name but I do remember that it starts with a doctor spotting a baby crying in a car on its own and then the father comes out of a church or clinic I think. The mother is a waitress or something and she's left him with the newborn, think they were living in a motel and are pretty much broke. Doctor offers him a job doing odd jobs at his home/ranch, and a place to live there.
I do remember later on the Doc invites a guy over to have dinner with them, pretty sure it was his lover, and the guy gets jealous.
It's sort of similar to Frog by Mary Calmes I think!!
Please please help!
