Raven Stratagem by Yoon Ha Lee

“Gen. Shuos Jedao, a 400-plus-year-old master strategist and mass murderer, was anchored to Capt. Kel Charis in the Hugo- and Nebula Award-nominated Ninefox Gambit. As this sequel opens, Jedao has survived an assassination attempt and taken over another military Swarm. While he is willing to fight off the Hanf who have invaded local space, his goal seems to be the destruction of the hexarchate, the rigid social and political structure that he feels has grown corrupt. Meanwhile, the hexarchate leaders are scrambling to control the man they use as their ultimate weapon. Lee has leveraged the adage that any seemingly advanced science can look like magic to create truly bizarre technologies, starting with a society based so rigidly on a special calendar that any who stray from its rules are executed as heretics. While the parasitic arrangement between Charis and Jedao created interesting character developments in book one, it shifts here to an even more unreliable narrator dynamic. VERDICT While there is plenty of gripping space opera action, the real pleasure of this series is the inventive worldbuilding.” — Library Journal, Starred Review
