I recently read through all of the Spellman Files by Lisa Lutz, and Something Missing by Matthew Dicks. Both were very entertaining to me because of the main characters and how unaware they were of how ridiculous and weird they were being—like when Izzy (spoilers up to book 5 of The Spellmans i believe) >!secretly lived in her brother's house<!, often casually left via window, and >!talked to her baby niece like any other person.<! And with Martin, how he refers to his clients as such, and has his whole system of doing things that he doesn't realize is kind of messed up.
I'm also autistic and find their ignorance of regular social behavior comfortingly relatable, if that makes sense.
Also relevant to possible recommendations like these, I love unreliable narrators, and if your suggestion involves one you don't need to tell me; I'll just try all suggestions and maybe will be surprised by one!
