The Antikythera Mechanism - The Antikythera Mechanism, #1

A renowned archaeologist, Arcadia Jones, gets a call about a famous artifact and its peculiar behavior, that embroils her in a foreign conflict featuring an extreme right-wing hate group called Golden Dawn. She races against time to recover the artifact against overwhelming odds, and at great personal danger leading her to the ancient Greek island of Antikythera. There she discovers ancient unknown ruins, hidden deep within the recesses of an undiscovered cave.
The cave plays home to technology unlike any ever seen on Earth, and Golden Dawn doubtlessly has sinister plans for its usage. And they have everything they need to make it work. The Antikythera mechanism is the key that will unlock hidden secrets older than the world itself. It's up to Arcadia and her unlikely friend, Alexandros, to stop them and the stakes may be higher than anyone thinks.
