When I say "out there" I mean books that cover topics and perspectives that are rarely hyped up in popular conversations around what people read. Like everyone can find a popular video recommending self-help productivity nonfiction or YA #relatable fiction but a recent fiction book that blew me away was "I'm thinking of ending things", it got a movie adaptation on Netflix but after the movie came out very little conversations about the book carried on. Fair warning, the book "I'm thinking of ending things" is a horrifically bleak exploration into the mental state of someone contemplating suicide at the end of his life and his reflections about himself and his mistakes throughout the years are not helpful if you're looking for a good time. But I've never seen a story go that far in depicting someone's mental state in that kind of situation so it blew me away but is also underrated imho.
