Anna and her famous scientist parents live on an island in the Indian Ocean. Anna finds a pirate's dagger on her usual afternoon swim. This prompts her to start investigating the mysterious sunken treasure of the Chivonne. But Anna's father's scheming colleague tries to shift the magnetic poles of the Earth. Are his motives above suspicion? Anna becomes tangled in these complicated adult matters. She is becoming accustomed to helping out her scientist parents where the earth's natural balance is concerned. This time Uranus Draak has developed his most lethal plan yet: With the new element known as Drakium, twin dragons have been constructed which, should they come into contact simultaneously with the magma layer in the earth's crust, will have unparalleled consequences for the planet.
