I really liked it but absolutely not for everyone. When I say it's dark it's DARK. I think it has a lot of interesting things to say but please look up a list of content warnings.
It was... okay? I had a good time in parts of it but it overall left me kind of cold. There's definitely a lot to think about in it, and I enjoyed chewing over many of its central ideas, but the page to page plotting was just okay. To be fair, I was so into the concept I don't know how it could live up. And, honestly, I don't regret reading it. Daryl Gregory is a talented man, with a very specific type of thing he likes to write about. If you want to read this book, try Revelator.
Really liked this one. I'll put in content warnings later.
Deeply sad, lonely, depressing. Encompasses a mood or idea I think about a lot.
