Jill Moss is about to walk down the aisle at her own wedding when the groom fails to show up. Distraught, Jill discovers that her fiance has been kidnapped and is being held for ransom, not for money, but for an elusive ancient artifact known as the Glass Dolphin. Along with her intrepid uncle, archaeologist and explorer, Neil Bryant, Jill must travel to England to pick up the trail. At the same time, she stumbles upon a clue that has been hidden for nearly two hundred years - the secret journals of Miss Cecilia Wardley, one of the first European women to set foot in the jungles of Peru. Guided by the clues in Miss Cecilia's diary, Jill and Neil set off to find Marco, aided by the gruff, rough and ready, Quentin McSweeney, underwater treasure hunter, and international security man, Bobby Buckingham. While Neil and Jill trek through the jungle, McSweeney and Bobby take the river. Their destination is the jungle compound of a notorious criminal who will stop at nothing to capture the Glass Dolphin. What the team discovers in their quest is beyond anything Jill could have ever imagined.
