Sold to My Best Friend’s Dad by Sam Crescent

Clara has had a crush on her best friend’s dad for years. She wishes she could get him out of her head, but Grayson Blackwell invades her every thought. The fact he’s a bully, rude, and dismissive doesn’t turn her off. It only fuels her desire to get his attention.
Grayson’s more than twice Clara’s age, not to mention she’s his daughter’s best friend. Any intimate entanglement would cross too many lines to count. The facts don’t seem to cool his desire for the young, curvy blonde. He decides to make a secret deal with her, one he hopes will help him end his obsession.

It starts with a contract, but things get messy once emotions get involved. Can they make their taboo relationship work or will it pull their lives apart?
