A trilogy of stories that shatter the myths of stereotypical islands of paradise. In Promises, during the late 1960s, the ketch, Mercy, sinks during a sea storm off Culebra near the Virgin Islands. Ciara Malloy assumes custody of her drowned fiancé's son and learns a devastating secret about the boy that changes her life forever. In Adrift, in the late 1990s, underwater photographer Lillian Avery gets caught in a rip current and swept out to sea off Kauai in Hawaii. In facing death, she finds a way to leave a message behind. Years later, in Reunion, the two former neighbors from Puerto Rico reunite on Kauai. A hurricane wreaks island-wide havoc. Ciara is missing, presumed dead. Among the rubble, Lillian finds Ciara's memoirs; a life history that threatens to expose tightly held secrets about the boy since the sinking of the Mercy.
