What I liked:
The plot and world building were interesting and different IMHO that lots of shifter novels. As there are more and more shifter/vamp/PNR, different is an excellent thing!
The characters were quite interesting, though I wish we had more insight into them. It felt very very rushed.
What I didn't like:
Wow, the story moved fast, too fast to be believable in the relationship category. Even though these characters had a history, their move into intimacy was really just not at all there. In fact, I saw very little interaction at all between them.
There was little dialog and all telling. It didn't flow or feel natural at all. The story choices and sentences felt really stilted, like a brand new author, though I see this author does have other works. I was unable to really lose myself in the story due to the writing. I struggled to finish this one.
I know this is the start of a series, and I hope the others will flow better because the setup of the coming war with the demons is interesting.
