Publisher's Synopsis
Twelve-year-old twin adventurers Cleopatra and Alexandra Dodge are reunited with their father and realize that two family heirlooms reveal the location of a treasure that is their birthright. When they set sail with Captain Tarboro on the Almira, they know they're heading into danger - the ocean is filled with new and old enemies, including their nemesis, the infamous pirate Felix Worley. But like a coral reef that lurks below the surface of the waves, trouble is brewing between the siblings.
