The lost Treasure of Aquila

Eleven-year-old Minne and thirteen-year-old Sam come from Stockholm to their relatives on Brač.

Their cousin Bianca also lives there, whose mom runs a small family hotel. The children are looking forward to their arrival, but they have no idea that they will soon become involved in discovering the secret of the pirate Aquilla, whose ship sank off the coast of the island in the 16th century.
