(Note: I received this book from the publisher as part of the Goodreads Giveaway program.) 
 Phenomenal. A great pop-science approach to how personal data is used and abused every day. The gimmick of walking the reader through a "lifetime" of data collection is a bit twee, and the conclusions seem a bit rushed- a bandaid meant to reassure that the reader that the world isn't as dire as it seems. I don't know that the book needs that. The meat of the book, though, is engrossing. A great book about math with no math!
