The first time Luca heard the Island of Inventions, he was very young, but the wonders he heard about sounded so unbelievable to him that they were forever kept in his memory. Since then, he never stopped searching clues which might lead him to that place of wonder. He read widely to collect information.

Taking a little from here and there, he got quite a clear idea of what the Island was really like. It was a secret place, where all the great men learn and invent together. To be able to join that select club, you had to have created great inventions. Only then could you receive the invitation.

To get a chance, Luca spend the years studying and inventing. Every new idea he got, he made it into an invention, and if there were anything he didn’t understand, he would seek help. Soon he met other brilliant inventors too, and he told them of the secrets of the Island. These young inventors would likewise dream of being sent “the letter”.

As time passed, the disappointment of not being sent the letter gave rise to even greater cooperation and help between them. Their inventions soon became known throughout the world.

But no invention came.

They didn’t lose heart. They continued learning and inventing, trying to come up with better ideas. Fresh talent was added to their group. One day, Luca, already very old, was speaking with a brilliant young man who had written to join their group. Luca told the young man the secrets of the Island, and of how he was sure that they would receive an invitation. Surprised, the young inventor said: “What? You mean this isn’t really the Island of Inventions?”
