Query: He did that...

I am upset that I wasted my money on this book. It was not very well written at all, and the story line does not flow. It jumps from one subject to another quite frequently, with no ties to bind them together. The grammar is hideous. I would like to know who edited this book, and have them fired immediately. My suggestion-do not waste your time on this rag.
