I loved the world created here. It is pretty realistic in its depiction of what would happen if supernatural creatures existed and people knew about it. Difference is never accepted..especially if the difference makes the other more powerful. So the mix of the different creatures and their interactions with each other I think I enjoyed the most. As for Mercy I loved her. Strong and independent but still soft in many ways. It will be interesting to see how the men in her life end...something tells me there will be a lot more coming. My only issue was that I found some parts of the story line confusing...especially with the motivation of the books big bad. Don't know..found it a touch too unbelievable. But overall...fun reading.
