Magic Castle

The book is a twin-set containing both an adventure story and a separate education section.

The main characters are a young boy called Arduino and a timid ghost, Harold. In his dream Arduino transfers himself to a mysterious castle ruled by an evil ghost, Herman. He meets Harold there and together they go through every crook and cranny of the dark castle with the intention of freeing the castle from the dastardly Herman. The mission is certainly not an easy one. Will they succeed?


The education section comprises answers to the following intriguing questions:

Why do humans yawn? 

How long is a good night’s sleep? 

Is it true that old castles are haunted? 

Does light that we can’t see exist? 

What is the speed of light? 

Why does smoke go up and a cannonball fall down?
