I read that a couple of years ago, Parson, and struggled to finish it, and I don't think I'd have given it your generous 3 stars. A brief note I made at the time:
Dorothy Hare, sexually repressed, down-trodden and wholly passive daughter of a domineering and snobbish rector, undergoes a bout of amnesia for no good reason, which allows Orwell to strip her of everything and send her out into the world in borrowed clothes and 2/6, the latter of which she promptly loses to 3 Londoners and petty thieves who adopt her as they make their way to the hop fields of Kent. She encounters destitution but a kind of comradeship there, is then shipped back to London where worse destitution follows, and – thanks to titled relatives helping and despite having no ability whatsoever – ends up teaching at a crummy private school, before someone comes and collects her and returns her to the parish, but with no longer any religious faith, only ritual. A polemic against poverty and the lot of women that might have been more hard-hitting if she wasn’t such a complete wet blanket all the way through, with no ideas or semblance of wit or intelligence.
Actually, with that "no good reason" I was perhaps being unjust, since there's a hint that a sexual assault has traumatised her, but that didn't help endear me to the plot, either. As you can see, though, I approached it from a feminist angle, not the religious -- I don't know enough about Orwell's take on religion to grasp whether he was also making a point about the Church of England and some of its pre-war clergy, but I certainly think it was the poverty aspect that was to the fore, as in his other work.
