David Scrimshaw reviewed City We Became by N. K. Jemisin
Review of 'City We Became' on 'Storygraph'
4 stars
The stuff going on in this novel has a multi-verse explanation, but I'd say you have to call it fantasy.
If you like an interesting story that has just about nothing in common with other fantasy stories you've read, this is a good choice.
I think it would be particularly fun for people who feel connected to New York City.
