Hello, I recently just finished writing a novel I've been working for two and a half to three years. I've gotten a lot of positive feed back on it, and I'm confident enough to take the story to the next level in hopes of publication. The problem is: I have no idea where to begin.
I've done a lot of research about copyright, writing contests that offer publication prizes, editors, etc, but I'm just unclear about what my next step as the author should be. My book is 300 pages long and falls under young-readers, fiction (same as genre as Harry Potter), so I can't find many contests where it meets the requirements (most want short stories). It also has a title that I'd like to protect, which requires a trademark. But, I want to do something with the book itself before I look into protecting the title.
Is there an order I should go about the publication process? Also, self-publishing was mentioned to me, but I have little idea of how exactly it works. Thank you for taking the time to read my question, and all answers are highly appreciated.
