The final installment of the Darkest Powers triology! As per usual, spoiler on previous books. 
 The ending of the storyline was wonderful. I loved the evolution of the characters, most especially, of course, Chloe. In this final book we really see her come into her own and come to grip with her new identity. She plays the perfect character for me - with an excellent balance between her strengths and her vulnerablities. I'd say this is my favourite part of Armstrong's writing - that her characters, albeit supernatural, are real and as such make the series much easier to believe as you read it. The same goes with Armstrong's numerous twists in the plotline throughout the entire series; normally, this type of conspiracy & etc could cause the book to be difficult to read but she plays with it so well that the concern is unfounded. 
 The way the novel ended makes me really interested in reading another. Mayhaps not one directly involving these characters but set in the same enviroment, maybe with cameos a la Tamora Pierce? Either way I greatly enjoyed this series and Armstrong's writing ability was wonderful.
