Query: I agree 100% with eheidel's review!

What's sad is that I actually DID try to read this book a second time, over a year after the initial attempt stalled after a couple of hundred pages. Once again, I thought it really good for some tens of pages and, once again, I became thoroughly bored with it and had to stop. It's finally time to sell all three books in this series.
