t's January 1972 but the sun is white hot when Willy May Michael's boat first kisses the dock of Mustique Isle. 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--one where Her Royal Highness can skinny dip, party, and entertain lovers away from the public eye.
Willy May, a former beauty queen from Texas--who is also no stranger to marital scandals--seeks out Mustique for its peaceful isolation. Determined to rebuild her life and her relationships with her two daughters, Hilly, a model, and Joanne, a musician, she constructs a fanciful white beach house across the island from Princess Margaret--and finds herself pulled into the island's inner circle of aristocrats, rock stars, and hangers-on.
When Willy May's daughters arrive, they discover that beneath its veneer of decadence, Mustique has a dark side, and like sand caught in the undertow, their mother-daughter story will shift and resettle in ways they never could have imagined.
