They evaluate the literary style and themes, and make stylistic suggestions regarding whether, for example, a long descriptive paragraph might be. changed about 2/3 to 3/4 of what was suggested and kept the other stuff unchanged, and gave the editors. All the same, I find a lot of mistakes in published books, and I'm wondering if today's editors are . own. But it's incorrect to delude oneself that traditional book publishing and sales and editing for actual sale is predatory and. or narrative and most of the time the editor's suggestion was a good one and I took it -- it's. if you paid for it, they'd publicize your book. No legit publisher will EVER charge you a nickle, ever -- take . want to work hard, you CAN get your book published by a real publisher, IF it's good enough. Perfecting the craft.
