The Foster Wife
Cindy Dorminy

Phin is content with working in his food truck all day and playing the field at night. But his business partner, Jay, offers him a bet he can’t refuse. If Phin can complete Amelia’s program without changing his ways, he will win Jay’s rare guitar. Certain his task will be easier than playing "Hound Dog," he agrees to enter the program.
With Phin and Amelia spending all their time together, her techniques begin to slip past his defenses. He might become her biggest success, but falling for a client isn’t supposed to be part of the deal.
