> the climactic scene is, essentially, people walking around a circular hallway a couple times

I feel like once you decide you don't like something, it's very easy to get reductionist about it in a way that makes it sound stupid or trite even if the reductionist statement is true. This summary to me is a quintessential example.

I liked the book alright, but certainly not enough to get into a debate about it. If you liked Leckie's other work, you'll probably find something to like here too, no matter your feelings on hallways. But maybe not!
