“Shades of Grey” by Jasper Fforde is legitimately the weirdest novel I have ever read. A few chapters in, I discussed what I had already read with my wife, and I said, “I think this might be from the point of view of board game tokens.” (It’s not.)
It’s pretty easy to get spoilery about this. The society is repressive, and something bad happened in the distant past, and sentence by sentence, page by page, you, as a reader, realize a little more about who they are and how their world works. This isn’t a happy book, but it certainly was fun.
