A very interesting twist, Leanan. And well-written, as always. :)
I did find the scene where Skywise finds the human responsible for her parents' death to have not quite enough changes to make me feel I wasn't reading very nearly the same story I had already read. True, it was Pike instead of Foxfur, but that's really the only difference. Is there anything about Skywise being female that might have changed the way the scene actually plays out? If not, perhaps that scene ought to be left out of this version.
I really liked the way Skywise being female changed her relationship with Cutter. The part where he brings her the heart is well done and very intriguing. That it would be Skywise he wants to "initiate" him rather than Nightfall was a great twist!
I am looking forward to seeing what happens when Leetah is brought into the picture. And Rayek. Possibilities abound! :D
