Beta readers wanted — dark adult cyberpunk novel (Part 1, ~35k words)

I'm an author looking for a few genre-savvy beta readers to react to the opening ~35,000 words (about a 2–2.5 hour read) of a completed adult cyberpunk novel — think Ready Player One's pace and voice told like The Princess Bride, but far darker and bloodier. ⚠ Content warning: extreme graphic violence and gore, crude sexual language, drug addiction, a child in peril, heavy grief, constant profanity. It's meant to be extreme — only apply if you genuinely enjoy dark/adult SF, grimdark, splatterpunk, or horror. You'll read at your own pace and answer ~10 short reaction questions (no line-editing — I want your gut: where you were gripped, where you drifted, whether you'd keep reading). Reading is distributed through BetaReader.io. A short confidentiality agreement is required before you receive the text. Name 3 dark/adult books or authors you genuinely love. How do you feel about graphic gore, crude sexual language, and a child in danger on the page? How fast can you read ~35k words and return written feedback? Give me a realistic date. Have you beta read before? What kind of feedback do you give? One line: what makes you put a book down for good?
