Dolly All the Time by Annabel Monaghan

 Dolly Brick is a single mom of son Gus and a kindergarten teacher in Boston. When the house where her father and disabled brother live, in Whitfield, RI, has a fire, Dolly decides that she and Gus will spend the summer there to help out her family. Dad owns a seafood store. And one day, after delivering seafood to a customer, Dolly comes across Stewart Whitfield, son of the wealthiest family in town. He has a flat tire and his phone is dead. Dolly changes the tire--and a photographer snaps a photo of the scene, which appears in a NY newspaper--the same newspaper that had just published a photo of Stewart's fiancee kissing another man. Stewart makes a deal with Dolly that she will pretend to be his new girlfriend for the summer and he will pay her $50,000--money she needs to replace her father's roof. And so begins a whirlwind summer of working at the seafood store and attending charity events. And soon Dolly is actually falling for Stewart, though she is sure that will not end well. But is Stewart also falling for Dolly and her son? It's a charming story of how 2 people who have always taken care of their families have to learn to put themselves first.
