I recently came across a book proposal that I’d written in 2013, one that was ultimately rejected because the publisher felt there were too many books on the subject already. So, I thought it might be helpful to share it with you, a guide to how to write a nonfiction book proposal. Note that I’m not suggesting that ALL book proposals should look this way. The publisher I was querying had specific requirements and I followed them. Having said that, this book proposal is fairly typical of what a publisher might want, although shorter than many others I’ve written.
