Query: Didn't get the joke

Building A Mystery is easily the worst book that I have ever read. It was so bad that I spent a large amount of time trying to understand how anyone could find it worthy of more than 1 star, and tried to understand why these people didn't see what was wrong with. I still haven't come up with an answer, try as I might. To me, this book was just poorly written, and I can't get past that fact. My loss, I guess, or maybe my money lost, I should say.
