You can't tell who read your book unless if they vote or comment on your book. And just so you know, when I started writing the very first was a rejection story, too. Although, I want to tell you that when you get reads and votes on a story that you thought up, it feels much better when people complement you on your books. If you need any tips that you think I might be able to provide you with, you can message me. P.S. I might not know most of what you want to know!
