Oh, wow. This is such a fascinating concept, and I want to read it and read it over again just to get the full effect. I love these types of epics, where the characters are so destined to be together that they make it through multiple lifetimes. It's normally a difficult genre to get right--a requirement for success basically mandating that the story feel EPIC--but you're a good enough writer to pull it off ;) This is such a refreshing read in the fandom! Will be recced <3
