In the summer of 1942, twenty-one-year-old Anne Calloway, newly engaged, sets off to serve in the Army Nurse Corps on the Pacific island of Bora-Bora. More exhilarated by the adventure of a lifetime than she ever was by her predictable fiance, she is drawn to a mysterious soldier named Westry, and their friendship soon blossoms into hues as deep as the hibiscus flowers native to the island. Under the thatched roof of an abandoned beach bungalow, the two share a private world-until they witness a gruesome crime, Westry is suddenly redeployed, and the idyll vanishes into the winds of war.
