Best ghost story I've ever read. Probably because it's not a ghost story in the classical sense of the word, but a modern book with all the necessary hook and payoff to make it a great read. But it's also a ghost story.
What I love about it is that people seem brutally realistic. People with power act like people with power. People who want to do better are flawed people who try and sometimes do a bit better. People with problems get into more problems. For the most part. But there's a bit of power and rightness fantasy in it too, to not make it completely bleak.
Really, really solid read (or listen).
