I am a nonfiction writer, and I've had three books published so far. I used this book to write my very first proposal, and I sold that book. I used it to write my second proposal, and I sold that book, too. I've recommended it to so many other writers that I thought I would finally write a review. When I knew absolutely nothing about the publishing world, when I didn't know how to start a proposal or what to expect from the publishing industry, this book made me feel as though I had a personal friend walking me through the process. This is a tough but wonderful business, and I feel privileged to be able to write full time. I don't think I would be doing this today if I didn't start with this book. My advice for anyone who wants to write is to work diligently, read constantly, and write the best proposal you can. A potentially fabulous book won't ever sell if the proposal is less than spectacular. Read this book, and every other book on proposal writing, then get to work. Best of luck!
