The Road to Dalton by Shannon Bowring

At the end of 1989, a car accident affects the lives of many in the small town of Dalton, Maine. There's librarian Trudy, who lives with her husband Richard (a doctor who runs the town's family clinic, which his father owned before him). Trudy's best friend, Bev, lives with her husband Bill, and is the head of the local retirement community. Trudy and Bev have a secret relationship that their husbands are probably aware of, but decide not to mention. Bev's and Bill's son, Nate, is a cop in Dalton and lives with his wife Bridget and baby daughter, Sophie. Other residents who figure in the novel include teenager Greg (who struggles with overeating and adolescence in general) and Rose, (who works at the police station and longs to be free of her abusive husband  Tommy). Taking place over a year, The Road to Dalton features a great sense of place for northern Maine and the everyday lives of its inhabitants. A great read-alike for Tin Camp Road and The Net Beneath Us.
