A literary circle is like a big group of friends who love to read books and talk about them together. Everyone takes turns picking a book they want to read, and then they all read it at the same time.
They might get together to discuss what they liked or didn't like about the book, what parts they thought were really exciting or interesting, and what questions they have about the story.
It's like having your own special book club, where you can share your thoughts and ideas with other people who love books just as much as you do!
