Off the coast of Georgia, archaeologist Lindsay Chamberlain excavates the 1558 wreck of a Spanish galleon. The ancient artifacts reveal evidence of a murder at sea. As she discovers clues to the identity of the four-hundred-year-old murderer, she is faced with modern-day pirates and two killings that appear to be tied to the excavation. Raging seas, pirates, snakes, and a ghost galleon make this an adventure for Lindsay like no other in her life.
