Honestly, there's not enough in this excerpt to give me an impression of anything. I know who wrote the book and what it's supposed to be about, but that's all. This excerpt did not get into content, so I can't tell you if it's good or not. It just read like more copy for the book, but it wasn't the book itself. Just can't say, but from the subject matter teased, it also doesn't sound like the book for me.
