I need books suggestion like the stranger by Albert Camus where he thinks he is a normal human but finds out his indifferennce isn’t normal.

I also explored the author's other works but isn't to my liking. Also too much complex wording leave a bad impression for me cuz I think they tend to be for native people only. And the main character in the book intrests me too much. And would like to find many other books or any form of writing similar to this one.
