I was surprised at how much I enjoyed this. Combination spy thriller and world-saving fantasy adventure with almost all compelling female leads. The fantasy is intriguing, and cleverly revealed to the reader gradually as the characters themselves learn more about what is happening. My only complaint is with the denouement; the reveals that worked well throughout the book feel a little deus ex machina when applied to the largest problems the heroes face.

Nonetheless it was a great read and I'm excited for the 2nd.
