Editing Work For A Rough Manuscript For A True Story

“I cannot say enough good things about Siobhan. She is without doubt the one of the best writers I have ever seen. She took my rough manuscript for a book, that started out as 250,000 words, and was able to cut it down to size (93,000 words) while maintaining the main themes of the story, the flow of the text, and the voice of me as the author. What can I saw but wow! She is extremely professional and is always willing to listen to your input as well as offer suggestions that will give you a top notch manuscript for publishing. I will work with Siobhan for a very long time to come. I would absolutely recommend her to anyone and already have!”
