I've read Jenna's helpful advice on creating Non-Fiction proposals. My concern relates to whether one should hold back on providing a great amount of detail in the proposal on a "hot" subject. It seems to me that, by providing sample chapter text and chapter descriptions, the publisher could politely reject your proposal - while forwarding it on to a writer who could run with your idea. I heard it happening to others where a fave writer (of the editor) will actually work on a book based on a proposal received by the editor. And, of course, the proposal submitter has no real recourse. Thoughts?
