Good afternoon! There are several sites where you can read novels online. I recently managed to the trap of ace read online at https://alphanovel.io/novels/billionaire/the-trap-of-ace-by-eva-zahan. Don't forget to check the terms of use and make sure the books you are accessing are legal and properly licensed. You can also buy books in a regular store. Each person chooses what he prefers.
Reading helps not only memory and health, but also develops writing skills. This is due to the fact that each book is written in a unique style, the reader adapts to this style and over time can distinguish it from others.
Unfortunately, at the moment the world is so modernized that people simply do not have enough time for books. There are many other sources of information.
