The book was hardcover with about 400 pages. However, it was printed double-spaced, so could have been done as a 200-page trade paperback. Because it was well suited as a group study book, it would have been a perfect fit for that target market if it wasn’t priced at $20.
Of course, the biggest problem he faced is that the book is already more than a year old—too old for most book reviews, contests, radio & TV shows, etc. Promotion on a new book needs to start eight months before the book comes out. There was little I could suggest at this point. The biggest window of opportunity for promotion had already closed.
