Aster Gray, the main character in An Unkindness of Ghosts by Rivers Solomon, is autistic.
From the author:
Odd-mannered, obsessive, withdrawn botanist and healer Aster Gray has little to offer folks in rebuttal when they call her ogre and freak. She’s used to the names; she only wishes there was more truth to them. If she were truly the monster they accused of her being, she’d be powerful enough to tear down the walls of HSS Matilda, the generation ship ferrying the last of humanity to a mythical Promised Land.
