Dolly All the Time by Annabel Monaghan

Dolly and her teenage son Gus are spending the summer with her dad and her younger brother Christopher to help with the cleanup after a fire in her childhood home. Located in the oceanside small town of Whitfield, Rhode Island, Dolly's family has owned Brick Fish House for four generations. Dolly plans on working there, but longs to expand the business with all the baked goods she makes. In a chance encounter, she meets wealthy Stewart Whitfield, who wants her to pose as his girlfriend for the summer after his fiancee cheats on him. Dolly agrees, since Stewart will be paying her enough money to replace the roof on her father's house. Their arrangement soon becomes personal as they develop feelings for one another. In her fifth novel, Monaghan writes another great beach read with in-depth characters that you really root for.
