If you like reading about self absorbed characters this isn't the book for you. I will not be recommending it. The writer is one to watch and if there are other books of his worth reading give it a shot but check out what you're buying. Not some "greatest hits" crap. I'm sure he has some redeeming qualities however it's hard to root for. Sorry author. It's been an agonizing 2 months having waited till now only to want my 2.99 back.

This is my first book review and I am quite surprised at how disappointed others were with this book. I've read many books on this subject in the past 20 years, including works by Michael Collins, Peter Kuznick (Who's Afraid of Red Riding Hood?) and even Andrew Wakefield. A lot has changed with respect to vaccines and our vaccination status today.

This was the very first book she ever picked up....and that is how I made it through the entire thing. She also likes reading books to "show" off her vocabulary words.....which by the way, are not even common words in most places. And if you look at her blog, her writing style resembles more a young teen than an adult. It's all over the place. And there isn't a single paragraph that doesn't begin with some meaningless word.
