James S.A. Corey – Tiamat’s Wrath: The Expanse, Book 8
This book’s theme is hubris. Though the book’s universe and most of the characters are secular, it has an underlying tone of angering the gods. The totalitarian Laconian regime is continuing to consolidate its rule over the entire 1,300-world ring gate system, and the main characters are continuing a small underground resistance in ways reminiscent of dissenters under Stalin and Hitler. But High Consul Duarte, in his hubris, attempts to wake up the forces that destroyed the civilization that destroyed the protomolecule’s long-gone creators. It goes about as well as one would expect.
There is also a bit of game theory involving the prisoner’s dilemma game. Duarte’s misuse of it results in a spectacular mistake about a third of the way into the book, and at least two facepalms from this reader. The book ends on a rather large cliffhanger, presumably to be resolved in the series-concluding book 9, which will likely come out in 2020.
