Raven Stratagem by Yoon Ha Lee

“Lee’s world building remains fascinating and complex, with a great deal implied in what is not said. The narrative of Raven Stratagem is a twisty one… It feels intricate, like a piece of clockwork in which every cog and gear has a job: it feels deeply thought, and powerful. Lee deepens here his interrogation of the themes that came so strongly to the surface of Ninefox Gambit: loyalty and trust, free will and self-determination, the personal costs involved in doing a right thing, and the problems of empire. Raven Stratagem offers an argument rather than an answer, and is more effective for it. If you liked Ninefox Gambit, this is a really great sequel, and an excellent novel in its own right.” — Locus
