Query: Boring book/ A waste of time

I depend on reviews on Amazon to decide what to read next. I'd noticed this book several times and finally purchased it. The rating was 4 stars. I only give it 1. I am sorry I wasted the time I did reading this book. I did manage to finish it because I thought that surely, something appealing would happen. It didn't. Don't waste your time and money on this one.
