Specifically between 2008 and 2009, fiction was the most popular book genre (source link). I was sort of anticipating that it would be fiction, mainly because with fiction, will can really open their ideas through compelling storytelling. It’s that kind of imagination that attracts the reader to the story. It’s having characters that you continue to think about even after you close the book for the day, and the story that you forge so many predictions about because you’re enthusiastic about the possibilities. As well as, the deep meanings you discover from the story that appeals to the things in life itself. With fiction, you can really go beyond what reality limits, while at the same time, retaining the same themes when find in life.
