Humankind is out in space, limited to mid-20th century tech while super advanced AI gods and their cybernetically enhanced angels control advanced tech, FTL flight and comms…oh, and Lovecraftian energies are destroying people and threatening worlds. Fun!

Having an autistic main character (and another supporting character) was very interesting as well, especially as a neurotypical (as far as I know) reader. The character’s differences in viewpoint and processing style were simultaneously an interesting look at a mental model I don’t know much about, and absolutely integral to the story itself.
