I have not read very much about this topic. I don't have experience with it either. If you do, I'd be surprised if this book isn't helpful. The authors seem to have a lot of experience and a lot of knowledge. They cover many topics and intersperse the text with interesting anecdotes. Perhaps their essays are not definitive, but they gave me a lot to think about.
At some point, getting your book published is probably a lot like math. You can't read about it, you just have to try it.
When my novel is ready to go out into the world, I am sure I will reread and refer to this book throughout the process, however it turns out, each juncture, each stage.
Wish me luck.
