“…every book has to be perfect (not too long or short and well crafted) and come with a marketing plan. Which means you have to have quotes, a website and a list of bookstores where you can do readings. Every book that sells to a major New York publisher, whether it is a mass market, trade paperback or hardcover must be able to guarantee 25,000 copies sold, or it will not be published by a major publisher.”
