This was a really enjoyable addition to the Mercy series, and Briggs' world as a whole. I quite enjoy the way Briggs writes vampires, and this book is absolutely filled with them, including Stefan and Marsilia. Other things to love about this installment: Mercy off on her own being clever, POV chapters with Adam, a delightfully rendered Prague, some more development on the witch, Elizaveta, some fun new characters (yay goblins!), and just enough little twists and turns to keep the pages turning. I did miss the werewolf pack, but there was still plenty of werewolfy goodness with Adam, Honey, Matt, and the Prague pack. All in all it was a lot of fun, and stood well on its own despite resting on a lot of series history. I look forward to the next in the series, even if it will be quite some time.
