Summer of Love by Katie Fforde

Single mum Sian Bishop decides to move out of London to the countryside to give her young son, Rory, a better life. After settling in to her rented house, she strikes up a friendship with her fiftyish next-door-neighbor, Fiona Matcham. Fiona introduces her to another mother, Jody, and includes Sian as a guest for a dinner party she's giving. The party is going smashingly well until Fiona's adult son, Angus, unexpectedly arrives. Sian is stunned to discover that Angus is actually Gus, the man she had a steamy one night stand with six years ago that resulted in Rory. Sian and Gus agreed that their encounter was a one-off because Gus was leaving on a long journey the next day. Afterwards, Sian had no way to contact him. Now, Sian still has strong feelings for Gus and wonders how she'll tell him and Fiona the truth. Complicating matters are Richard who's waiting in the wings for Sian to say yes to be with him and obnoxious Melissa, Gus' childhood friend who would like to be something more. Summer of Love is light, enjoyable English romance.
