** spoiler alert ** 
 When people begin randomly killing other people--and often themselves in the process--nobody thinks much of it at first. But when the violence becomes a full-scale epidemic, England shuts down and the violent people, called Haters, are rounded up for execution. However, the Haters don't believe they're haters; they're the next step in evolution, and it's them or the humans. The war has begun. 
 I went into this book expecting rage zombies like in 28 Days Later, but these aren't zombies. These are otherwise rational people who truly believe that their lives are in mortal danger and they must kill or be killed. 
 The premise of the book was fascinating, and overall I enjoyed it. I do, however, have a few gripes: 
 * First person present tense. Sometimes it works. Most of the time it doesn't. In this case, I think it worked in the last quarter to half of the book. In the beginning, it just made the story drag because the narrator is pretty much trapped in the now. 
 * The Haters are far too rational, IMO, for what they're doing. They have a weird combination of complete understanding that they've changed, that there's something different about them, that the kill-or-be-killed instinct they have in regards to family and friends is completely false (at least until they've killed a person and their family and friends actually do turn on them). And yet they continue to matter-of-factly discuss how they must kill every "normal" person in order to have any chance at a life. I wasn't sold on the dichotomy. 
 * Absolutely no sympathetic characters. I get that Moody was aiming for real people with real quirks and foibles, but everyone in the book was self-centered, impatient, rude, and generally unlikeable. There are no heroes here, only everyday people you'd meet on the street--and then be annoyed at. 
 Moody did manage to make the Haters far more sympathetic than the humans; true, the Haters killed people, but in the first rush of becoming Haters, they truly believed that their lives were in danger. By the time the main character becomes a Hater, the government is in full-out attack mode, rounding up the Haters and essentially sending them to death camps. At that point, their killing became a fight to survive. However, there are quite a few murders perpetrated by the Haters that were absolutely unnecessary to either of these scenarios. 
 I understand that this is the first in a series, and I'm undecided right now whether I'll read the rest of them as they come out.
