An attempted murder at the Florida State University ice core laboratory leaves geology professor Mark Malloy wondering who wants him dead and if they will try again. Fortunately, Mark is leaving for the Greek island of Santorini to spend the summer resolving the mystery surrounding the lost island of Atlantis. He believes Atlantis' fate is linked to the mysterious annihilation of the advanced Minoan Empire, the cradle of European civilization, on the island of Crete. While studying the Thera volcanic eruption on Santorini, Mark teams with Greek archeologist, Alexandra Papadopulos. As the summer field season draws to an end, he must return home to face the unknown person who wants him dead.
