Tucked into the southernmost curve of the Caribbean, Mustique is a private island that has become a haven for the wealthy and privileged. Its owner is the eccentric British playboy Colin Tennant, who is determined to turn this speck of white sand into a luxurious neo-colonial retreat for his rich friends and into a royal court in exile for the Queen’s rebellious sister, Princess Margaret. Willy May Michael, a former beauty queen from Texas, seeks out Mustique for its peaceful isolation. Determined to rebuild her life and her relationships with her two daughters, she constructs a fanciful white beach house across the island from Princess Margaret. But when Willy May’s daughters arrive, they discover that beneath its veneer of decadence, Mustique has a dark side.
