Wow, where is everyone? I enjoyed this story, though I can definitely see where Unblinking and ChairmanDances are coming from. Personally, the pacing didn't bother me, possibly because I got caught up in the story very quickly. I was invested enough that I really felt her hurt when her childhood playdate came back changed, and I also felt nervous and indignant when the sprites decided they would "help" by playing a joke.
One element that I really liked was how each daughter retained the core gift of her maternal line, but its expression and outflow changed with each generation.
