"Too Like the Lightning" by Ada Palmer
This book was interesting. “Interesting” can be used to mean a lot of things, and frequently to dissemble. But in this case I mean it simply—it was an interesting book because Palmer creates a fascinating world that the novel spends most of its time exploring. The book is also unflinchingly pretentious, very well-written, and quite slow. It’s often described as political science fiction, because the futuristic setting is mostly a vessel to explore how society and politics have changed.
