I have ghost written many ebooks that are published on Amazon as well as a few of my own self-published. My own are under the name of Elaine M. Foust. Some of the other ebooks I have ghost written are under the name of Olivia Sanborne. I have written/ghost written and co-written over 30 books and ebooks in the last 3 years. A couple of them are highlighted in my profile. If you look through my profile, you will see that I am a very versatile writer: articles, blogs, novellas from romance to children's books and ebooks that include how-to books, pope's bio, self-help, health, etc.
If you want specific samples emailed, I can do that too. I have never written about horoscopes, but I have read tons of books about astrology. It is one of my interests, obviously. I look forward to hearing from you to discuss this project.
