Google Books is like a big library. It's a web site that stores millions of books so you can read them on the internet. You can find books in Google Books by typing in a word or phrase that's related to the book you're looking for. For example, if you type in "Princess and the Frog," you might see lots of books that have the word "Princess" or "Frog" in them. You can find books written by different authors, and also learn more about the authors by reading their biographies.
