Perfection of the Paperclip

When I first saw this title, I though people will write a book on anything. However, after exploring, much more to this book. Check it out. 

My other thought, however: how the f..k does a guy get a book like this published. Who decided on it? For those of us who keep trying, would love to know the publishing story. 

Let's don't take away from the author, however, more power to him.
