Thieves attempt to steal one half of an ancient, cryptic manuscript from Jeffrey's and Cindy's parents. But they fail to break open the safe and run off when they hear the police siren. In their haste to get away, they left behind their satchel containing the other half of the old document.
Why were the crooks so eager to steal their parents' half? The kids put the two pieces together for the first time in hundreds of years, and upon decoding the secrets it holds, embark on an underground adventure that shows them what the ancient visitors left in a cave a thousand years ago.
But danger lurks below—they must battle treacherous caverns, their own fears, and must learn to work together as a team, all while being chased by villains who have their own agenda.
Set in a time before smartphones and the Internet, Doubloon Cove: The Secret of the Ancient Visitors is a thrilling adventure full of danger and revelations. History, mystery, and action come together in this compelling story; it is Nancy Drew meets the young Indiana Jones meets the Goonies.
