This is the second in the Age of X series. I really enjoyed the first book in the series, Gameboard of the Gods, and I had high expectations for this story. Fortunately, Richelle Mead delivered. Without going into spoiler territory in this part of my review, I will just say the pace was great, the characters are memorable and I love the concept of several gods battling it out with humans as their pawns. There are so many fantasy books where there are mentions of religion and gods, but rarely do the gods make an appearance. In this series they are pulling the strings behind the scenes, and we get glimpses of them. I hope in the third book they all come out! I am going to give this book 4 stars.
