Sunny Alvarez and Mac Reilly always seem to find trouble in the south of France. This time, all the trouble began in Monte Carlo. Sunny's relationship with Mac is in jeopardy and Monte Carlo beckons. Soon Sunny is pulled into a web of intrigue involving a series of robberies of high-end jewelry stores. Then there's her wanna-be-new-friend, who turns out to be a sociopath, involved in the sale of sex and in blackmail. Plus there's Sunny's old friend, movie star Allie Ray, who owns a vineyard in France and who comes to help sort Sunny out, while at the same time sorting out the life and appearance of her old friend, Pru Holster, with a makeover that not only changes her dowdy overweight appearance, but changes Pru into an amateur detective. If Sunny doesn't untangle this plot, she might end up an unwitting accomplice to theft, blackmail and even murder. When Mac shows up, he's ready to do anything to get Sunny back, not the least of which is to solve the crimes and save her life.
