Half of my family is actually from rural PEI, so I can unfortunately assert that Montgomery's writing is very accurate re: Christianity and classism and the like. Less so these days, but not as much as you might think (or hope).

Funnily enough, while I've read quite a bit of her works, I haven't got to Jane of Lantern Hill yet. It's been years and years since I read it, but I suspect you might like The Blue Castle. I might be remembering it more fondly than it deserves, mind you, but yeah.

(Oh boy. Yeah, I'm not gonna be a fan.)

Also thanks for the heads-up re: potential triggers.
