It’s a not-so-well-respected rule in Hollywood that what happens on location stays on location. But when a hot young leading man winds up dead in his Rome hotel room, his costar’s life is about to go off the rails in a very public way—even by celeb standards.

At the tender age of twenty-three, Mercy Talbot has won an Oscar, battled addiction, wrecked more than her share of cars, and burned down her house. Her look-alike mother keeps her on a tight leash (and fueled with an endless supply of OxyContin and cocaine) and her producers demand a grueling schedule. By the time she stumbles across Juliette Greyson, a Hollywood insider on a much-needed vacation, Mercy is surrounded by photographers and about to emerge drunk, high, and naked from a public fountain. Whisking her away to an idyllic Tuscan ‘retreat,’ Juliette is about to discover another rule of Hollywood: wherever the starlet may go, the drama will follow.
