Jean Hubbard is a syndicated health columnist, her British husband, Mark, a successful advertising executive, and after more than twenty years together they revel in a sabbatical on a remote tropical island. But when Jean discovers a salacious love letter addressed to Mark, she realizes that she has misdiagnosed some acute pathologies in her own life. The long idyll of their mutual ease is over--but a more vivid and compelling quest has just begun. Looking for answers, Jean goes undercover with a surreptitious e-mail correspondence that propels her on to alarming, and illuminating, adventures of her own in her adopted home of London and her native New York.
