It is amazing how much information--about freedom, privacy and certain aspects of technology--is included in this engaging thriller. There are very disturbing scenes involving a US government organization and teenagers that probably would have seemed far-fetched to a lot of Americans when this book came out in 2008, but which, in light of the daily happenings of the US in 2025, seem almost mild. There is so much food for thought here. I sincerely hope that this book is read by many, many teens.
