Dragnet Nation by Julia Angwin (2014)

Dragnet Nation: A Quest for Privacy, Security, and Freedom in a World of Relentless Surveillance
Subtitled: A Quest for Privacy, Security, and Freedom in a World of Relentless Surveillance.  Angwin is an investigative journalist who explores the many ways we are being watched and recorded and what we can do about it.  
Short answer?  Not much.  

Angwin looks at how our private lives are under watch and how our private data is being collected by the bushelful, then goes deeply into security and hacker circles in order to figure out how to evade being tracked.  Fascinating and eye-opening.  

A good companion to Brandwashed by Martin Lindstrom.  Also, Angwin's sources are marvelously documented in full detail.
