Books play a huge role in a person's life. they help to find answers to questions, have a good time. with a book you can visit all corners of the planet from the comfort of your room.
There are many types of books. The most famous ones are: adventure, novels, tales. My favorite type is romance novels. People who write books are called authors. The most famous Russian writers are Ivan Turgenev, Alexander Pushkin, Leo Tolstoy, Anton Chekhov, Mikhail Bulgakov, Ivan Bunin and others. They have already died, but left a huge reminder - their books.
My favorite book is "the Little Prince" by Antoine De Saint Exupery. The book is dedicated to a friend of Antoine Leon Werth when he was little. I think this book should be read by anyone. This is a very interesting and sweet story about a tiny man who lives on a small planet and every day rescues her from a terrible baobabs. The book describes the adventures of a small boy. Quotes of the Little Prince is very famous all over the world.
Most of the books I take in the library. This year I started to read a lot. I go to the library at least twice a week. Most often it is the school library, but sometimes my mom brings me books from the library of Lenin. This is the biggest library in my city, I think.
