Robert Silverberg's "The man in the maze" is a cool science-fiction book based on the Greek play Philoctetes. Iirc it's a very short story (maybe about one or two hundred pages), I don't remember the exact length but I recall reading it in one sitting. It is a very character-driver story where the "maze" itself is an allegory about mankind, isolation and disability, but it is very much enjoyable as a casual read as well.

The protagonist ("man in the maze") is an astronaut who has been somehow cursed to always radiate its emotions in such a way that others, even his family, find repulsive, so he self-exiles to a remote and long-dead planet to live the rest of his life in isolation. But when an alien species makes hostile contact with humans, he is needed again, as his "curse" is the only way to properly communicate with them and maybe convince them that humans are sentient beings and thus their equals.
