Magic Triumphs by Ilona Andrews

What do you do when an ancient evil returns to your world, threatening to kill everyone you hold dear? An evil who causes thousands of people leave their homes to be boiled. Well, Kate decides she needs to make a deal with the devil, aka her father.

I hope that this is the ending to the Kate Daniels series while starting one with Julie and Erra and launching Hugh's. This is just a perfect bookend to the series bringing everyone together in a satisfactory way.
