Having an objective person, like a book editor, look over your book is a powerful way to produce outstanding work. An unbiased person won’t hold back. A stranger reading through your writing will be able to pinpoint areas that need more detail or are grammatically incorrect. Although you may be an amazing writer, even the finest authors understand the importance of improving their craft. An experienced book editor can advise you on different word usages to better improve the way you communicate. Your reputation as an author is dependent on your work. Style issues, grammatical errors, and communication problems all detract from your work getting the recognition it deserves.
