Looking for Atlantis - Colin Thompson

The story is set in an old family house, where a boy mourns the recent death of his seafaring great-grandfather. He leaves the boy an old parrot called Titanic and a ship 's chest. The sea chest is full of wonderful treasures and many things relating to the lost city Atlantis. The idea of Atlantis haunts the boy. It's only a fairy story, says his parents, but somehow the boy knows Atlantis is true and he can find it. The book is the story of the clues he follows as he looks for Atlantis, and his eventual discovery of a truth richer than treasure.
