Query: Shallow characters, thin plot,, poor grammar, a real yawner

This book was primarily an essay preaching Mr. Cook's doom and gloom view of the economy, using the pretense of a fictional novel. Character development was poor to non-existent. Grammar and punctuation was poor, and dialog was choppy and shallow. Many little vignettes with characters and situations totally unrelated to the rest of the "story" were included for some reason, but they did nothing to bolster the story line.Don't waste your time.
