The witch best friend is the best part of this book. 
A vampire, a shifter, a Norse god (who is built and sounds like Thor but is supposed to be like Loki), add a Vampire priest who has fallen from faith...give them a shifter girlfriend who is more than she seems and seems to be broken and then throw in some Supernatural apocalypse type stuff and demons....then you have this complicated storyline. Time is fluctuating so much it's hard to keep track of when things are taking place and there are so many tropes taking place it is like someone emptied the cupboards of everything and put it all in one bowl... I had high hopes going in but literally only finished the book for the sake of finishing. It was a good idea originally but it just became too much...maybe less slices
