** spoiler alert ** "Dog Blood" is the second in what I believe will be a trilogy, following the incredibly disturbing "Hater". "Dog Blood" is every bit as violent and full of horror as the cover would lead you to believe, continuing the story of a society coming apart at the seams as the population almost overnight divides into two camps, Haters and Unchanged. Seemingly ordinary people suddenly become unstoppably homicidal, driven by a powerful hatred to kill everyone they encounter who is not "like us". "Hater" covered the early stages of this phenomenon; in "Dog Blood", several months have gone by, and the world is on the brink of apocalypse. All semblance of civilized society is gone, and the survivors face a reality in which "kill or be killed" has never been a truer sentiment. I found "Dog Blood" overall to be more tightly written and edited, and couldn't put it down. Not at all a fun read, "Dog Blood" is none the less compelling, and definitely not for the faint-hearted.
