I was a little underwhelmed, honestly, especially given how much I liked the previous two stories. There weren't a lot of surprises. No twists or new or interesting ways to look at things. The seemingly harmless oath is indeed harmless. The good guys are strong and brave and undone only by treachery. The small-minded petty people are revealed to be small-minded and petty. Then we end with the final scene from "Hamlet," except that instead of dying tragically, the protag just gets kicked out of the place where nobody likes her and her only two friends have just died. (Really, why would she have wanted to stay? Around about the time she "realizes" that they intend to exile her, I was going, "So? Sounds awesome. This place kind of sucks anyway.")
It was nicely written and it passed the time, but I didn't find it particularly affecting. It felt like this was a backstory written about a (perhaps overly) beloved badass female swordswoman character from some other piece. (In particular, the ending lines about finding "many more" pieces of red silk felt odd for the character as we'd seen her. She had previously been conflicted and insistent on the scarf because of her mother, but then suddenly she's actually just vain and wants lots more silk scarves? I felt like I was supposed to go, "Ah, that's why [famous character from other story] is always wearing those fifteen scarves in every shade of red," but since I didn't have that kind of point of reference, it just came across as an abrupt shift in her attitude.)
