The Gate House by Nelson DeMille

The Gate House is a sequel to DeMille's 1990 best seller The Gold Coast, but can stand alone if you haven't read (or don't remember) The Gold Coast. John Sutter returns to Long Island for a funeral but gets caught up in the privileged world of his ex-wife, the ultra-rich and ultra-spoiled Susan Stanhope. There's also the matter of a little unfinished business with the son of the mafia don that Susan murdered. It's a long book and fairly predictable. But it's well written and the sarcastic humor of the narrator is worth the read. I enjoyed it.
