The novels that a 17-year-old boy reads can refer to the following types: - Science fiction: This type of novel usually has high-tech elements and fantasy plots that can bring readers unlimited imagination and desire to explore. I recommend the " Three-Body " series," Wandering Earth ", etc. - Fantasy novels: These novels usually have magic, mythology and other elements that can bring readers surreal feelings and imaginations. I recommend the Harry Potter series, The Lord of the Rings, etc. - Historical novels: These novels usually have historical backgrounds and characters that allow readers to understand different cultures, thoughts, and history. - Modern novels: These novels usually have elements and characters of contemporary society, allowing readers to understand the current social situation and human feelings. - Science fiction and fantasy could also be combined with modern elements to create a richer and more interesting story, such as Star Trek and Twilight.
