I thought this was an adorable fic! I have a few things though:
In the beginning, you mentioned almost every single action that the characters did, which gets repetitive and boring. It didn't happen so much at the end, but I think that you were much more comfortable and into your story by then, so...yeah. I do that too.. I think it's a matter of being comfortable with your own writing, so kudos to you for overcoming it!
Another thing: I think that Wilhelmina would call Alexandra 'Grandmother' or something, because in 'Daughter of the Blood', it mentioned that Jaenelle insisted on calling everyone by their first name, but I don't think her sister would have.
One last thing before I praise it some more: if you ever decide to re-do and re-edit this fic, I suggest maybe going a little more in depth with Wilhelmina's thoughts and feelings.
I really loved this fic, though. Please keep writing!
