Look, I sympathize. It is genuinely difficult to have your POV character be Totally Wrong about something in a way the audience can detect but he is completely unaware of, and have that work. But one of its failure modes is “your POV character is a blithering idiot,” and I’m afraid that’s how I felt in this instance.
It probably didn’t help that everybody else in the novel was coming across as abrasive and unhelpful, too.
Sorry. I really wanted to like your book, but it just didn’t work out.
