Looking for Dark and Disturbing

I’m drawn to books that explore dark, disturbing themes: psychological trauma, moral ambiguity, obsession, and twisted relationships. Some of my favorites have been Sharp Objects, My Dark Vanessa, Speak, Such Dark Things, I Hunt Killers, and Annie Bot. I love stories that blur the lines, explore the psyche, and feel raw and emotionally unsettling. I also really love poetry, especially free verse writing styles. If it’s beautifully written and deeply unsettling, I want to read it.

Any recommendations?
