To start writing bestseller fiction, you need to understand your target audience. If you're aiming for young adults, for instance, you might want to include themes like coming - of - age, friendship, and first love. Read a lot of bestseller fictions in the genre you want to write in. This will give you an idea of the current trends and what readers expect. Also, don't be afraid to take risks with your writing. Try out different writing styles and voices until you find one that suits your story best. And always be prepared to rewrite and edit your work multiple times to make it as polished as possible.
Begin by finding your own voice as a writer. This is crucial because it will set your work apart. Then, do your research. If your story is set in a particular historical period, make sure you get the details right. When it comes to the actual writing, start with a strong opening. It could be a gripping scene or an interesting dialogue. Build the world of your story carefully, whether it's a real - world setting or a fictional one. And remember, the key to bestseller fiction is often emotion. Make your readers feel something, whether it's excitement, sadness, or anger.
