I have a little brother who is 11 years this year. We get on

I have a little brother who is 11 years this year. We get on well with each other and have had a good times together. Several days ago, I bought a book to him. The book is written by those which have won Nobel Prize and it aim to help children learn about the unknown world. Before I bought the book, I have read it. I felt that it is a good book for him, because he is interesting in new things and has so much questions. I hope that through reading book, my brother can learn more about the world and know how to do a good person.
