Milton, Angels, Mortals: a Story Idea | by Adam Roberts: This will be a very busy day, so I don’t have time to engage with this as fully as I desperately want to do, so consider this a bookmark, and these as first thoughts: 

• In this scenario, angels are bitcoin and people are money. 
• The angels/humans relationship looks a good bit like that of Elves and Men in Tolkien’s legendarium, except that Elves do have children (just not many of them). 
• Maybe in light of that one element of this history would be the fallen angels trying to figure out how to have children. Would they pursue this technologically? Or would they, like the people in The Children of Men, make do with surrogates? 
• Adam envisions the faithful angels remaining in Heaven with God, but why would they do that? If in the orthodox Christian understanding (faithful) angels are among us, why wouldn’t they be in Adam’s imagined world? 

More … eventually.
