After extensive research and multitudes of rejections, I've discovered the secret of a successful book proposal. There are nine steps to successfully selling your novel and each of them should be included in your proposal, in the order that is laid out below. If you follow this procedure, you will answer all of the publishers questions in a way that they can not refuse to contract your work. The only reason that you could possibly get a rejection, if you follow these steps, is if you have targeted a publisher who does not handle your type of story, you have an unsaleable subject, or you simply did not write it well. After your greeting, begin your first paragraph by answering question number one, then move on through the entire nine step procedure.
Publishers make money selling books.
It's that simple. Find out who else has written a book or articles on the same subject that your book deals with. Story ideas, movies and books tend to be trendy and usually fill the market in waves until public interest has peaked and then moved on to new horizons. Give examples of other publications that deal with your subject and then tell the publisher why your proposal is unique. If none of these apply, then omit this section, however, if this is the case, you might reconsider attempting to take on this project to begin with.
