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 Guardians of Time Trilogy
Villain Decay: Marduke. He starts off as a genuinely creepy murderer with half a face, and becomes a sort of mutated pig.
Wangst: It's mentioned in the first book that Rochelle's past isn't pleasant, but that she still has a chance to do good. Then she starts to narrate, and it becomes somewhat more difficult to sympathize.
