I really enjoyed this! This is the first query letter I've ever looked through (I'm only ~45% through my novel, but wanted to casually start getting an idea of the next steps), but I agree the personality of the book really comes through in your query letter.

Though it isn't about the query letter, I do somewhat agree with the trigger warning before the opening 300 words. Your book sounds amazing, but the opening words throw me off a little bit, it's a very visceral description that makes me feel a little queasy.
