Book name: Matilda 
Matilda is a book about a girl who knows how to read adult books. And can do all her time tables by the age of 4. The dad said she was naughty and then pulled some pranks on him but he did not know it was her. When she went to school she learnt a superpower that she could pick up things without touching it.
The teacher is really poor. Mrs Trunchbull hurls somebody like a javelin just because she had some pigtails in her hair.
I would say it is a good book and I think it the age should be about 5 years old and up.
