A writer is very biased about his book because he is the author and nobody likes to get criticized for their work, but it is a complete lack of intelligence to publish a book without getting it proofread by an expert. An author after finishing his final draft should look through the best book proofreading services for book writers and hire a proofreading expert to get their draft analyzed critically. The proofreader will check it thoroughly, mark and edit all the grammatical and spelling mistakes and formatting errors and make your final draft perfect and publish-worthy. A well-written book is free of any mistakes.
