Jack Hitt of The New York Times Magazine writes, “On any given week up to half of any non-fiction bestseller list is written by someone other than the name on the book. Add those authors who bury the writer’s name in the acknowledgements and the percentage, according to one agent, reaches as high as 80."
. . .You may actually be in the majority. And whether you are a housewife, a doctor or a celebrity, your chance of getting published, or even better, of having a bestseller increases when you use a collaborator.” says Mahesh Grossman, author of Write a Book Without Lifting a Finger.
A ghostwriter is a writer who is paid to write a book that is published under the name of another person. If a co-author is used, then that writer gets a credit on the cover or title page of the book.
A ghostwriter can:
Get your book written while you are focusing on your job and the other important things in your life.
Help you meet deadlines and get your book completed on time. The longer you wait, the more money you will leave on the table. Getting out the message as soon as possible means quicker results. You may also have an idea whose time has come and--if you take too long--someone else will publish a book based on the same idea.
Organize your material. A ghostwriter can take that pile of scrap paper and help you turn it into a book.
Provide that particular skill writing for a wide audience takes.
