The End of Mr. Y

I require a very high bar for spec fic books based predominantly on quantum mechanics, but I think Thomas did a very good job here. She clearly learned her stuff, and uses it sparingly and deeply when used. I'm less a philosophical expert, but it seemed to be handled similarly. All of that being said, while many books use quantum mechanics in service to the plot, Thomas seems to be writing more of a Sophie's World style, where the plot exists to advance her thoughts on quantum mechanics and philosophy.

While this seems to have turned a lot of people off, I found her completely forthright about it: this is a book about a main character who is writing her thesis about novels that are thought experiments. This is a novel that is a thought experiment: let's say we could enter thoughts. If that were possible, what would it mean for how thoughts are made? What would that say about what it means to be conscious? Is what we learned from this thought experiment generalizable even in a universe where thoughts aren't a manifest place that can be visited? Those are fun questions to ask and explore.

When she veers away from that core, the book really falls flat (the love story? The random officemate who was into evo bio and got totally dropped, even though I really wanted her to integrate into the main plot line?), but that's OK, because it's not supposed to be a proper novel. My only real complaint is the ending kind of petered out.

I thought Thomas had interesting thoughts about what it means to think, what defines consciousness and whether emergent consciousness is possible. I was intrigued by the thought process of whether defining phenomena mathematically instantiates them or merely defines them and I think she explores this in a particularly deft and nuanced way.
