A new home can bring new friends… new adventures… and new dangers. Boone Fischer and Emily Durand have settled down in the Turks and Caicos—specifically, the picturesque island of Grand Turk. But a chance encounter with a dive boat from a nearby island leads them to pull up stakes again, if only temporarily. The couple takes the Lunasea across to South Caicos—The Big South—an island with a rich history… not all of it virtuous. An unidentified body discovered in an underwater cave system may have been the victim of a murder, but the manner of death is bizarre. Boone and Emily find themselves ensnared by events once more, but resolving this mystery may come at a steep price.
