Just for comparison: Start of Darkness was 112 and I'm pretty sure that number includes the forward and preface.
This is just so so good. I can't even organize my thoughts around it properly I've got so much I want to say about it. One of the best things I've read all year for sure. I need this sitting on my bookshelf.
And I'll say it. Better than Start of Darkness. It's close for sure, but this has the benefit of being written ten years later.
