Set in mid-2000s San Francisco, Cory Doctorow's Little Brother brings a tale of what can go wrong when yuo have a society that values compliance over independence.
A story of technology innovation, hacker culture, information sharing and data freedom all set against the backdrop of a modern-day terrorism nightmare. Cory Doctorow highlights a number of different things in our everyday world that allow other people to learn more about you, to track you and build a profile about you. These are extended to the next level in Little Brother talking about some of the what-ifs and could-bes that today's technology could allow.
