Athena Crowley is an ordinary eleven-year old girl who lives in an extraordinary place: The Atlantis Resort, in Nassau, Bahamas, where her father Robert is a marine archeologist. He s the man who discovered traces of the Mythical Lost City of Atlantis, for which the hotel is named. Athena s mother was lost years ago when a freak whirlpool took her away. Athena goes to school, rides the slides, and helps out at the hotel s dolphin encounter... a fairly normal life. But everything changes the day an old turtle starts talking to her, and Athena realizes that she can communicate with sea creatures. Determined to understand her roots, Athena takes a risky journey to the undersea kingdom of Atlantica, where mer-people rule, humans are slaves, and dangerous and thrilling surprises await her.
