When the Angels Left the Old Country

I thought this was really lovely! As a goy I did kind of wish for a little more backmatter or footnotes to explain some terms (esp as a YA title) but I think I did OK from googling on my phone + context clues.

I saw reviews comparing it to Good Omens which on one hand I get but on the other I think it does this a disservice, because it's not as funny as Good Omens but it's going for more of like a fable vibe.
