Query: Massive Education

I caught an interview with Ms Garrett on NPR awhile back, and I was intrigued by the discussion, so I bought this book. I was at first rather daunted by the 622 pages.This is a riveting 622 pages. The mystery, the subterfuge, the politics, the sex, the violence, and of course, the massive expansion of my science knowledge is just wonderful. This book will thrill, amaze, shock, revolt, hold you in it's claws and then keep you awake at night all at the same time. A wonderful companion to contemporary political, military, climate and scientific studies, this book is a real eye-opener. I recommend it to anyone wanting to expand their knowledge and view of the world at large.
