Louise Bheag and Benjamin reach the Mexican coast, where they hear their father is searching for Inca gold But all is not what it seems! Before long the twins are in the middle of the jungle, in the city of the Feathered Serpant. And that’s only to begin with! France, the year 1660. After the death of their mother, Louise Bheag and Benjamin are sent to an orphanage in Paris. Louise Bheag is an unruly girl; she prefers the sword to the darning needle. And Benjamin is no soldier; he prefers books and sea charts. Together, they decide to run away from the orphanage and to go to sea in search of their father – knowing only that he is the captain of a ship away at sea.
