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 Hollows
Alternate Character Interpretation: Nick. Is he a bumbling Smug Snake egoist who used Rachel solely to have an in to demons and magic, or does he only appear that way because it's all we can see from Rachel's narrative? There may be a lot more to Nick and his motives than the reader sees, because Rachel does not see every aspect of his life.
Fan-Preferred Couple: Several. Rachel/Ivy is a favorite but Rachel/Kisten and Rachel/Trent are also common pairings. Less common but present are Rachel/Jenks and Rachel/Al pairings.
Fetish Fuel: Rachel bites Kisten with "caps", fake vampire teeth, to make the sex kinkier. Rachel is also passionately fond of high-heeled boots.
Internet Backdraft: The revelation that 'Kim Harrison' is a pen name for Dawn Cook has created an odd amount of backlash among some fans on various forums. Whether or not this is large enough to create a Broken Base has yet to be seen
Moral Event Horizon: Many for the villains including Piscary's off-screen rape of Ivy and Lee allowing several innocent people to die in an explosion on his boat. For some fans Trent's murder of Brett also evokes this trope. Kisten originally setting the bomb on Lee's boat to begin with seems to have avoided this because to most fans Beauty Means Goodness.
As if we needed more proof that Ku'Sox is a complete bastard, in his latest exploits he kills an infant. Keep in mind, this infant would've even been useful to his plans at the moment since it had Rosewood Syndrome. He just did it to mess with Rachel cause she was rescuing the nursery of terminal babies he stole. Guess Kim needed to stress that yes, in a world of grey and grey morality he has absolutly no redeeming qualities.
