This book suffered from mid-series book syndrome. The main plot of the book was only partially resolved and much of the book went to set up events to come. That is not to say the book isn't enjoyable, it is, it's just a set up book. Still the Kane siblings are as awesome as they were in the first book, and I love the way this book shows how they've had to grow and assume resonsibilites since (and because of) the events of The Red Pyramid. And I love how Egyptian Mythology (and some Egyptian history) is melded to the bones of the story.
