Matilda is apparently a children's book but I think that it also shows a hard reality whose cruelty only adults can value.
On the one hand the books tells a story that, unfortunately, is quite common for special or just different people who feel that nobody understands them and they are seem as if they belonged to another planet.
On the other hand Dahl shows a situation that nowadays is more and more frequent and it is a society that values the most superficial things, like physical appearance and money and, however, neglects some of the important values like respect, affection and sympathy.
This book is easy to read because of its structure which is divided into short chapters where the author tells us highly gifted chil's exciting and funny adventures. It is very interesting and entertaining and I would recommend it to readers of any age.
