http://www.amazon.com/gp/product/006122814...id=W2BSNZ9TV7JN is a new book on waiting, and looks interesting (despite the title.) But you don't write a book because there isn't one out there-- since while you are writing one, a similar one could be published, so you never have a guarantee of no competition-- you write because you have a story to tell. If you have a story, tell it. I do think you should try shopping it around before starting the labor of writing. If nothing else, you'll get free advice about what the public likes. ← I saw the title you mentioned and didn't think it was too interesting. Half the book is about a romance with a chef. Let me say, from the beginning, and this may sound crazy, but my goal is to win a James Beard award with the book. I want it to be that good.
