Eleanor Oliphant Is Completely Fine was a book that threw me just because the main protagonist had such odd perspectives.

Listen For the Lie by Amy Tintera is written with segments of it like a true crime podcast. Highly recommend it as a listen.

Ive been reading a lot of books that aren't written traditionally. Taylor Jenkins Reid books, Evelyn Hugo was written as an interview, Daisy Jones and the Six like documentary, etc. Dungeon Crawler Carl is LitRPG and best as audiobook (written primarily as such). Of Monsters and Mainframes was written with computers as main characters. Super fun.

So many good books out there. Please report back on what you've enjoyed the most!
