"The Invention of Hugo Cabret", by Brian Selznick
It is written for the children, the main characters are children, a mystery has to be solved,.
You can see beautiful drawings like this one...
...and the story leads us to the cinematographic universe. The adaptation to the cinema was realised by Martin Scorsese., which makes me all the more reason curious to look it. Even if I was not transcended by this book, I think it is a good reading for children .
