I thought this would be more of a techno-thriller. It turned out to be more of a man vs man or a man vs himself sort of story. Interesting, compelling, and extremely thought-provoking. It has a One Second After kind of vibe in that the core disaster is one that is entirely too plausible and leads to events that are entirely too likely. By the end of the book, the most troubling concept is just how conceivable everything described really is.
