I liked a lot of the nitty gritty details of the superstructure, but the “adventure” through it overstayed its welcome, in my opinion.

I thought of a thing the main character should have tried, and it kind of ruined the whole “rescue” subplot for me. (Worth noting this was basically the main plot.) Even an offhand comment about why it wasn’t feasible would have been fine. I’m tempted to flip the spoiler switch and go into it, but it’s not that big a deal. There were also some motivation problems that I had a hard time accepting, but overall, minor quibbles in a great “book”.

Of course, I do wish I’d been able to read it rather than listen to it. The voice actor is great, but just not the way I’d prefer to consume. Oh well.
