Query: The greatest book ever written!

The courage it took to write this book - a lifetime of work! Powerful, important information about voter fraud that goes as far back as the assassination of JFK - and continues today. All the dots are connected in this one - including a miraculous chapter of Floor Thirteen in the World Trade Center - and this book was published in the year 2000! Every American NEEDS to read this book - NOW.
