And today's diagram . . .
My first two efforts to clarify Caitlin's relationships with all six of her mothers. Each one, you'll note, crossed out as I failed to get them right.
And here's what it properly looks like... Caitlin's relationships with her mothers, Aerth, Faerie, the physical and the spiritual and of course her (adoptive, in some ways symbolic) daughter, Esme. Because to understand her mothers completely, she has to have a daughter herself. At this point, at last, the entire novel is so clear in my mind that I can encapsulate it in a single diagram.
