Getting readers onto the hype train that is the love of your writing is the hardest part of being an author. To overcome that barrier, consider compiling an anthology of short stories and one or two sample first chapters. Give away some of those short stories anyway you can. For example, I’d suggest putting some of your short stories on your website so anyone can read them. If you put a little explainer at the end of each story, telling readers where they can get more like this, you will have solved the onboarding problem.
