Right, I'm not sure what to make of this book. Personally, I find the 1- and 2-star reviews quite unfair, but I'm not so enthusiastic about this book and find that the 5-star reviews are exaggerating. I leave 4 stars because I genuinely enjoyed reading it (and because if I left 3 stars I'd feel like I'm not really taking a stand). I was feeling rather curious about how events would develop and about the actual "apocalypse" that lead the world to be the way it is described. Said that, I have the impression that the author was trying to connect the events in the book with what's happening now in the real world, but the leap is far-fetched to say the least. Also, there's a big element of implausibility in the historical side of it - as well as in the description of the enemy, ruthless but too perfect to be human. I recommend the book if you want to read something entertaining, just don't expect it to be mind-blowing as some 5-star reviews seem to suggest.
