Any books which emphasise the feeling of being alone? It doesn't need to be a direct theme of the book. Maybe the main character who wanders quietly or calmly around and have musings that feel distinctly his, but all that feels somehow as if he is alone. Stuff like that. Preferably the book isn't edgy or about misery of a guy.
I am John von Dorf. Deals with inability to relate to peers as a result of being displaced from people that you can relate to, but ultimately ends up revealing that the protagonist is trying to relate in vain, because he can't even relate to his childhood friends.
I don't want books with themes mainly about loneliness
Too miserable and seems angsty. I tried reading it for hundred pages, but all there was ironic humour and boring apathy to everything.
Saw some good responses so I will probably check it out.
This probably hits closest from what I know. Maybe being stranded lays hood ground for being alone, but the idea is that the protag doesn't reflect a lot about it, he just does what he does. Something that let's you to reflect on loneliness. See the movie Coraline, for example, tough where she meets various characters, she still gives off a feeling of being alone in all the events and surroundings.
