Three days in june - Anne Tyler

Gail Baines is long divorced from her husband, Max, and not especially close to her grown daughter, Debbie. Today is the day before Debbie's wedding. To start, Gail loses her job—or quits, depending who you ask. Then, Max arrives unannounced on Gail's doorstep, carrying a cat, without a place to stay and without even a suit. But the true crisis lands when Debbie shares with her parents a secret she has just learned about her husband-to-be. It will not only throw the wedding itself into question but also send Gail back into her past and how her own relationship fell apart.
