With a BA in English and History and an MA in Creative Writing (for which I was awarded a Distinction), I believe I am the ideal candidate for this job. I have five years' experience writing and editing full-length novels and would be able to write in any of the following genes: fantasy, romance, thriller, horror, action, children's books. I would not be able to finish a novel in 7 days, but by the end of 7 days, I would be able to have established an outline and a project-plan, during which I would keep you updated at all times.
Although I am a British native, I am more than happy to adapt my writing to be Americanised, including all American spellings and culture. My History degree has also given me excellent research skills; using these, I will be able to research any aspects of American culture and/or the book that I am unsure of.
Please get in touch and let me know if I am the right fit for your project.
