Pros:
I like the variety of supernatural creatures and their interactions amongst each other
The mystery and stakes of the plot interested me and once I was hook it kept me

Cons:
The author writes like she HATES people with substance abuse issues (drugs, alcohol). They are constantly objects of the main character's scorn, butts of jokes, and victims of meaningless violence. It happens so often and so much (will not spoil) that it distracts from the story and makes me (someone with these issues) feel pretty crappy about myself.
This reads like the author doesn't have much writing or even READING experience. it's like she read one or two medical dramas or perhaps watched some Grey's Anatomy and thought "Hey I could do that!"
