Here is Bronwyn Fryer's advice to you ghostwriters: When you talk with authors, make them tell you the level of commitment they have to the book on a 1 to 5 scale, 5 being the highest. If the score is below 3.5, understand that you’re running a risk. Writing a book is like getting married; it demands an enormous amount of time, trust and mutual obligation to see the process through to the end.
