Kathryn Ann Kingsley is such a fabulous writer even though her books kind of follow the same formula.  MMC is undeniably evil and unhinged but lovable and the FMC has to come to terms with her truely neutral alignment.  Her sense of morality doesn't necessarily follow what we think of right and wrong. 

This can make some readers uncomfortable if they have a strong sense of what acceptable behavior looks like.   What seems forced is not always unwelcome.  Sometimes being overpowered and helpless is what is desired.  KAK likes to walk that line and it makes the spicy scenes VERY hot. 

While themes are repeated in her books she builds such great stories and worlds and sometime other characters around the romance that each story feels fresh and unique.  

I could read 100 stories with Simon Waite or Aon or Valroy, and now, Julian Strande in whatever new plot she devises and I would eat each story up like it was new.  

Maybe I relate to her FMC type.  I have a history that makes me look at life with more cynicism and acceptance and approach life as tones of grey not black and white.
