Query: Shattered Air

While one reviewer couldn't put the book down, I can no longer pick it up.After many attempts to enjoy the book, the most thrilling thing about it was being able to skip over a great many pages to uncover the story...any story. Alas, I was confronted with geological detail, characters whose pretensions, conceits and vanities left them flat and pedestrian, 4th rate socialogical commentary, and I still haven't found what was promised in the Publisher Description located on Amazon.Simply put, the book should be free thus people will get their money's worth.The Author is a decent writer and I feel bad that this is story he concentrated on.
