Query: Why I decided NOT to buy this book.

After reading all the positive professional reviews, I was looking forward to reading this book. But, after reading the "real" people reviews, I decided not to. Especially after reading one review that said this book was "as shallow as Bridges of Madison County". THAT book received rave professional reviews as well, while I thought it was the most inane piece of drivel that had ever wasted printing paper. Though I enjoy fiction, I still like substance in my reading. I'll pass on this one.
