Beyond Selidor

What I really want to see (but for which I can't think of any examples off the top of my head) are stories about human beings falling in love with the deities that they worship, and the weirdness that would ensue, particularly regarding their own attitudes about religion.

Dude, yes! I would eat that up!

I've also been fortunate enough to have a lot of people write fic for me about many of these pairings over the years!

That's wonderful!

Have you read Hambly's James Asher vampire series? The romance between the main vampire character and James and his wife Lydia (I very OT3 them) is not explicit, but I feel like it's so aware of the differences between them because of Simon's immortality. It never forgets that vampires would be deeply weird and other. (So many vampires these days are just regular people who happen to drink blood.)
