Buckle up, because this is a weird one. In a far future version of our universe, humans have built giant soul-eating AIs and now worship them as gods. Through their cybernetic post-human “angels,” the gods enforce their dictates on the people and root out any heresy, which is belief in a reality that doesn’t match the existing one. This is important because too much exposure to the “Outside” can spread like a virus, destabilizing actual reality and bringing hyperdimensional Lovecraftian horrors from Outside. In this world, autistic lesbian heroine Yasira just wants to make useful scientific inventions and hang out with her amazing girlfriend, but is unwillingly drawn into a battle between her former mentor and the AI gods for control of reality. I loved the prominent role that neurodiversity played in this book, and the recurring point that society is built on lies that we all agree on together.
