Query: Horrible Book

This book is disgusting. Don't be fooled by the title. I was skeptical, but figured, for ~$15, why not take the chance there might actually be something useful in this book.This book is nothing but fluff and vagueness. Grandiose claims that go long on promises, but come up short on deliverables. 50% of the way into the text the author is still claiming that more details will be provided later on - by the time you get to the end of the book nothing useful has been provided, just a bunch of buzz-words and phrases to give the illusion that you actually learned something you could apply.DO NOT BUY THIS BOOK.
