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.
Strangled by the Red String: In Star of Doom, Sonja is in love with a fellow mercenary, Daron (though it takes her a little while to admit it). Note, that's in love; we don't see them fall in love, which presumably happened during the month or so they knew each other before the book opens. Because of that, and because what we see of Daron makes it seem like he's not really Sonja's type, the romance doesn't feel earned.
