Go to a website that sells books. I like Books-A-Million, personally, but you choose where to shop. If you do not want to buy a book, check out your local library. Ask your library if they have a digital app to check out books--bonus, no late fees! Peruse the categories, and read about what the book is about. Pick 3-10 books that stand out to you as books you are interested in reading. Once you have narrowed down your list, read the first few pages. Oftentimes, this is an option before you buy a book. Pick one of the books to start reading.
