very exciting book. i loved the technical explanations, the historical background, the references. if you are a boingboing.net reader you can almost see where cory got all the stuff from, but there is even more to it. although the book is aimed at younger readers there is a point where even hard s.f. aficionados will enjoy it (just give it some chapters). i liked the way in which a lot of arguments around 9/11 are presented and meditated upon. it’s not simplistic, it’s not just the view of a lefty activist that hates (rightfully so most likely) what has happened, but there is a lot of empathy; empathy for the suffering and the loss and the incertitude and where that can take you as a human being. yes, there are a lot of emotions and difficult arguments presented in the story.
i got a hardcopy of the book because i wanted to support the author and the fact that he released it online for free and under a creative commons license, i also want to pass it around. yes, buy it (or download it), read it, and pass it to young people in your life.
