Query: Total waste of time; don't waste your money

This book is horrible. They just threw some stuff out to get a book published and should be ashamed of themselves. So naturally I was curious when there were so many one stars yet so many 5 stars...as another reader identified, the ones with 5 stars are quite suspicious -- almost all have not reviewed a single other book and the one guy has read over 3,000, but all have five stars. How could that be, either his standards are very low or he has another agenda. Beware, don't waste your money!
