Transgressive fiction has a way of getting under your skin and staying there. Bret Easton Ellis, Cormac McCarthy, Chuck Palahniuk, Flannery O'Connor — these writers didn't ask for permission to go dark. They just went. So we want to know: What's the one book that made you feel genuinely uncomfortable — and you loved it for that? Did it influence your own writing? Would you recommend it here, or is it too much even for this crowd? Drop it in the comments. No judgement. This is exactly the place for it.
