Okay little one, let's talk about books in Spain. A book is like a big piece of paper with writing and pictures inside, it tells a story or teaches you new things. In Spain, there are lots of books that are written in Spanish because that's the language they speak in Spain.
A long time ago, people used to write books by hand, so it took a really long time to make just one book. But now, we have something called a printing press that can make lots of copies of a book all at once. So, books are much easier to make now!
In Spain, there are lots of places where you can buy books, like bookstores or libraries. These places have big shelves or bookcases full of books for you to choose from. You can pick out a book that looks interesting to you and then you can buy it or borrow it from the library.
One of the most famous Spanish books is called "Don Quixote" which tells the story of a man who thinks he is a knight and goes on adventures with his friend. Another popular author in Spain is Pablo Neruda who wrote poetry.
There are also lots of children's books in Spain, written just for kids like you! They have fun stories and colorful pictures. Some popular Spanish children's books include "Elmer the Elephant" and "The Three Little Pigs" (which is called "Los Tres Cerditos" in Spanish).
So, that's how books work in Spain, they are everywhere and you can read them in your own language!
