This question is somewhat difficult to answer due to the ever-changing tastes of readers. However, we can make some educated guesses about what will be popular in the next year or two.
In terms of genre, fiction remains at the top as readers want to explore new worlds and lives through engaging stories. Science fiction and fantasy are expected to remain popular, as well as thrilling detective and suspense fiction. Romance will also likely stay popular, as it is a genre that is ever-evolving, keeping readers engrossed.
Non-fiction will also have its place in the coming year, as readers seek educational, informative books. This can range from biographies and autobiographies to books that provide insight on the latest trends and movements. Historical non-fiction and books about current affairs will also be trending.
Ultimately, there is no one-size-fits-all answer to the question of what types of books are popular in 2022. However, it is safe to assume that readers will have a variety of fiction and non-fiction options to choose from.
