Doubloon Cove

Jeffrey's and Cindy's parents are college professors and believe that there is a thousand-year-old mystery regarding Vikings in Massachusetts right here in Doubloon Cove, Massachusetts. But their peers ridicule them, so they are too afraid to pursue it. So it is up to Jeffrey, Cindy, Steven, and his brother Frederick to solve the case. But they must battle dangerous caverns, their own fears, and must learn to work as a team, all while being chased by crooks who have their own agenda.

When Stacy is told that her father has been kidnapped, with the demand that she hand over the secrets to the location of the Freemasons’ (and possibly the world’s) greatest ancient treasure, she enlists the Doubloon Cove gang to get her father back. But things don’t stop there. The teens must race the bad guys to find the treasure first, while running from the Illuminati, evading the police, and working behind the Freemasons’ backs.
