Very well written. Mr. Donnelly nails the human aspect. The first 4 chapters were so intense that I actually had to put the book away for a few days - which is extremely rare for me. You find an empathy for the protagonist (Ian) that just draws you in. The story reads a lot like Kurt Vonnegut, though not quite so satirical. It does however bring a believable future if we continue the path of technology we're on. Not necessarily a read for everyone, but I enjoyed it.
