Very interesting book, written for YA, but interesting for adults. The book was published in 2008, and the events at the G20 conference in 2009 seem to show much of the concerns that are raised by Doctorow have been borne out, not in the indefinitely distant future, but right now. The other reviews give excellent summaries, and seem to fall in two categories: depressingly realistic assessment of the surveillance society, surprisingly hopeful possibility of citizen response, positive reviews, and significant deficiencies in editing, and the quality of the writing, character development, negative reviews.
But five stars for the ideas. I would characterize this as a book of ideas, and as such, the five stars. The events at the G20 demonstrations the very next year illustrate this, see http://www.guardian.co.uk/world/2009/oct/04/man-arrested-twitter-g20-us
recounting a specific case of the security apparatus cracking down on a man using social media. Do you remember when the media and politicians were all celebrating the use of social media by the public during the Arab Spring? And no significant comments from most of these folks when the FBI dropped on Eliot Madison like a ton of bricks for doing the same thing in the USA. The activities in Tahir Square captured the attention of the world, while the eventual nationwide HomeLand Security coordinated crushing of the Occupy movement by heavily militarized police in communities across the country passed by without raising much of a ripple.
On a hopeful note, the positive reviews shown here recounting the incredible enthusiasm with which young folks have received this book.
