Product Description: Joshua's life was pretty average until his archaeologist father was reported dead in a plane crash. Josh's dad had been searching for the Mayan Codex, said to contain key information about the 2012 Mayan prophecy foretelling the end of the world. Was the crash simply a tragic accident, or is there more to his father's death than the authorities are willing to tell him?
