Okay, kiddo, let's talk about literature in the 21st century! It's like when we read books, but these books were written more recently than the ones we usually see on our bookshelves.
In the 21st century, people started to write in different ways. Instead of just writing novels and short stories like they used to, people began to experiment with new forms of storytelling. They started to write things like graphic novels, which are like big comic books with lots of pictures and words. They also began to write stuff like interactive fiction, where the reader gets to make choices that affect the story.
Another thing that's different about literature in the 21st century is that people started to write about different things. In the past, authors would write about things like love and war and adventure, but now they write about things like social justice and mental health. They also write about things like technology and the environment, since those are important issues in our world today.
One other thing that's changed about literature in the 21st century is that people are using new technologies to create and share their work. For example, lots of authors now publish their work online, so anyone with an internet connection can read it. And some authors are even using things like Twitter and Instagram to share small snippets of their writing with the world.
So that's a brief overview of what literature looks like in the 21st century, kiddo! It's all about trying new things, writing about important issues, and using technology to create and share stories.
