These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Parasol Protectorate
Ho Yay: Madame Lefoux, who first appears in the second book, is fairly obviously attracted to Alexia, who is rather oblivious.
Moral Event Horizon: Felicity informing Lady Kingair of Lyall's involvement in the Kingair Pack's treason, with the specific intention of ruining Alexia's marriage when Lord Maccon found out.
Suetiful All Along: Many people, including Alexia herself, consider her plain. However, when you add together all her described traits, you get a very attractive woman. (This is part Values Dissonance, since Victorian English find her Italian heritage unattractive.)
