Silver vessels

"What happens when a bunch of teens get together at the Florida Keys for an unforgettable summer of Treasure hunting? After obsessing over a history lesson at school, Joshua enlists his two best friends to travel to the Florida Keys for the summer to hunt for the treasure of Our Lady of Atocha, a Spanish treasure galleon and the most widely known vessel of a fleet of ships that sank in a hurricane off the Florida Keys in 1622. Staying up, sneaking out, and searching for a legendary buried treasure is just the beginning of the summer of their lives!"--Amazon.com.
