I have a book published by a small press. It was never reviewed by any of the major kidlit reviewers prior to publication. However, an editor at one of them later told me she would have reviewed it had she known it wasn’t self-published. The book received positive reviews. I’m working on new projects, but still feel this project didn’t get its best shot. Is there a process for submitting a small-press book to large publishers when sales have not reflected the book’s potential?
