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 Three Worlds Cycle
Squick: Ian Irvine seems to take sadistic glee in being sadistic towards his characters. Look at everything he does to Flydd. And Jal-Nish. And Karan. And... well, you get it. Sadist.
Wangst: Minis, Tiaan and Nish especially. Nish improves a fair bit over the course of the series though.
