What Character-Driven Fiction Should I Read Now To Feel Inspired?

I'm in a mood for something bleak and philosophical. Any suggestions for a character staring into the abyss, but written with beautiful prose? I want to feel existential dread through someone else's eyes for a change. My own life is stressful enough, but somehow that makes it more appealing.

For a sharp, witty, and modern character piece, 'Normal People' by Sally Rooney is essential. It follows Marianne and Connell from the end of high school through university, tracing their on-again, off-again relationship. The plot is simply their lives—miscommunications, class differences, personal traumas, and the magnetic pull they have on each other. Rooney’s genius is in her microscopic attention to social cues, internal anxiety, and unspoken thoughts. You understand every hesitant glance and poorly worded text. The characters feel painfully real, with all their awkwardness, intelligence, and capacity to hurt each other. It’s a book about how two people can be fundamentally important to each other’s development, even if they can’t quite make it work conventionally.
