In the early 1900s an important ship sinks into the Caribbean Sea, just as the Virgin Islands are transferred from Danish to American rule. Orphaned by the sunk vessel are two sisters and their half-brother, now faced with an uncertain identity and future. Each of them is unusually beautiful, and each is in possession of a particular magic that will either sink or save them. This novel chronicles three generations of the island family from 1916 to the 1970s, set against the emergence of Saint Thomas into the modern world.
