The author of ten published novels, I have over fifteen years editing, proofreading, and ghost-writing experience. In that time, I have worked with all kinds of different writers - from first-time authors to the far more established - working on all kinds of different projects: fiction, non-fiction, memoir/biography, self-help books, scientific and academic texts, etc. Recently, I edited the memoir of a Wolf of Wall Street type character, a rag to riches story of a man from an impoverished and abusive background who conquered the financial markets. The client was so pleased with the end-result, he's currently querying U.S. agents.
In terms of my working practices, I will edit your 461-page memoir in three stages. Firstly, a basic edit to eradicate any typos, grammatical lapses, the repetition of words/phrases, etc. Secondly, a more developmental edit focusing on the structure, story development, tone, voice, etc. And thirdly, a final read through to ensure your book has that essential professional polish.
I use Track Changes in Word, will provide an interim assessment of the book (typically the opening few chapters) within twenty-four hours of receipt, and can make a start right away.
I look forward to hearing from you.
