The Gate House by Nelson DeMille

Ten years ago, socialite Susan Stanhope Sutter shot and killed her Mafia don lover, Frank Bellarosa. She and her husband, John, divorced; he sailed around the world for three years and lived in London for seven years. She moved to Hilton Head near her domineering parents.

John is back in the US, on Long Island specifically, because he’s the attorney for an old lady, the last half of the former gate house couple, who’s near death. Frank’s son, Anthony, tries to recruit John back into the Mafia. Susan has recently moved back to the guest house (her former home with John and the kids) on her parent’s former mega-estate and she and John reunite as lovebirds. Will John work for Anthony? Will Anthony avenge his father’s death?

The story is long and the middle is a tad boring, but it reads quickly, especially near the end. The author’s dry, sarcastic wit is present throughout the story and had me smiling or laughing the entire time.
