For all that this story started well, creepy and gripping, with religious lockdown of women (hence comparisons with The Handmaid's Tale), the second half fell into well-worn tropes and predictable plot twists.  Which might be cool - I don't read much horror so I don't know how much is expected in the genre versus how much is overused. 

I found the character development uneven, the leaps of logic unexplained, the dialogue a weird mixture of formal (One character literally apologises for using a "colloquialism" which felt very out of place in an otherwise normal chat with a stranger). The religion-based lockdown on women's behaviour and movement only applied when the author wanted it to? 

On the other hand, I still finished it, I still wanted to know what happened, I still wanted the bad guy to get their comeuppance and the good guy to win. I think it's a good, scary debut.

This is firmly horror, to the point that my brain was giving me utterly pedestrian dreams such as going to the shops, and doing my favourite work tasks.
