This is pure, self-indulgent Mary-Sue-to-the-extreme competence porn. It’s decently written for an online fic, but it’s also full-on A Connecticut Yankee in King Arthur’s Court. The logic isn’t always (or often) logicing, it’s really just the protagonist winning and being all kinds of amaaahzing when the odds are stacked against her, complete with “importing ideas from our world will make me successful” etc.
But hey – long, fun, self-indulgent is sometimes what you need, and it’s free online.
Plot summary
Beware: full spoilers! Also probably incomplete and possibly incomprehensible.
