Top 10 Sci-Fi and Fantasy Authors on Social Media

One of the most popular book genres on the market is sci-fi and fantasy books and you can find plenty of people talking on #BookTok about them. Sci-fi (short for science fiction) is based in speculative fiction with imagined elements that don’t exist in the real world. Fantasy tends to have similarities to sci-fi, but usually adds magic to the imaginative world. Books like “Harry Potter” and “The Lord of the Rings” fall into the fantasy genre.

Since these genres are so popular, you can find plenty of aspiring and current authors talking about their fantasy realms and fictional characters on TikTok and Instagram.
