In a little under my lifetime this has aged into a standard post apocalyptic grimdark meets Oregon trail that half had me expected zombies by the end, with a heavy dose of Butler reminding the audience that she gets the Baptist mindset. I usually prefer the second world approach, so for me the worldbuilding wasn't as profound as something Jemison would do, and the prose was nice and functional but not transcendent like Leguin. I don't think the spiritual elements make as much as a natural fit as in Russell, but to be fair this work is a great deal more coherent.
