Pestilence

The four horsemen have arrived to declare the beginning of the end of the world, causing most technology to break down, and then they disappeared. Now Pestilence is back and is spreading a Plague everywhere he goes, and only Sara is brave enough to try to kill him - or so she thinks. She was not the first one to think that, or to try, not knowing Pestilence cannot be killed. Now she's his prisoner, and he's taking her with him all over the world to finish his task. Can she sway him to change his mind?
I had some conflicting feelings about the characters in this book. Pestilence is supposed to be neutral, unfeeling, and indiscriminating. But he decides to show mercy to Sara because he thought he saw a sign. But, even knowing that, seeing Sara chip away at that part of his exterior kept making me hope for a redeeming act from him. And I think that was the mistake Sara kept making - romanticizing Pestilence when he was clear about his intention to make her suffer. However, I was happy at the end when he actually broke down and decided he was done with his task, and that humans can, in fact, be redeemed. I am looking forward to reading War next.
