I think the author doesn't understand puzzles, of any kind. Many of the ones in this book have more than one solution, which would make any puzzle pointless and unsolvable. BN must stop selling it. I bought it a week or two ago, my BN order number was 4037276245. Apparently it's not possible to give a rating of 0, so I had to check 1. The book isn't "poor." It's completely worthless. I won't let this rest - I'll keep checking until it's removed from sale.
