Yeah no.
The two stars are because it absolutely had redeeming features (great schoolchildren, cosy village life, fun friend Rose), but they really don't make up for the severe flaws.
Maybe it should only be one star due to what I'm saying in the next paragraph.

Let's be clear: The two instances of transphobia played for laughs are not OK in any way.
I'm also really not a fan of all the casually biphobic comments (at least the bi character gets to push back against them once).
Then there's the bad classism (awful clichés about working class people) and casual misogyny. No thanks.

This is down to taste, YMMV: The kind of stilted tone of the narrator is genuinely amusing overall, but for me really really doesn't work during the sex scenes.

Lastly, I'm glad that the point of conflict is solved quietly in the end. For the last quarter of the book, I was really scared it would lead to an awful public blow-up and luckily it did not. Smart choice. The ending is very well done, I think.
