Query: This book was poorly written

I thought 'The Day of Reckoning' by John Murphy was terribly written. The subject matter throughout the book changed very erratically, and the book ends up not really going in any direction. The irregularities made it hard not only to follow along with the text, but also to hold any interest whatsoever. For example, John Murphy expresses his views on the how shoddily the tragedy was handled by the SWAT team in one sentence, and in the next sentence he brings up Monica Lewinsky. In addition to the poor writing style, I also felt that this book holds no real merit. To say the least, this book did not do any justice to the Columbine tragedy.
