The worldbuilding was more expansive as we get to see and learn more about the magic of dragons and of spirits. Rachel Aaron has created a really unique setting for this series and the backstory of how dragons ended up on earth was truly captivating. Even though all these sometimes across as an info dump, I was to happily lapping it all up to be really bothered about it.
The development of the characters was wonderful. While Julius was still as nice as ever, you just cannot mistake him for being weak and definitely not stupid. With the machination of his oldest brother, who was one of three dragon seers ever in existence, Julius was placed as the central chess-piece towards an endgame which relied on his unique undraconic personality to succeed. It was frankly quite masterful.
Marci's magic potential grew by leaps and bounds, and what was even more intriguing was the development of her relationship with her spirit (which comes in the form of a ghost cat). This is definitely one human to watch out for. The growth of her romantic relationship with Julius was also handled well. I hate plot devices where characters don't communicate and talk things through. Fortunately, this was not an issue here.
Julius' older siblings were truly the icing on the cake. Crazy Amelia the Planeswalker, quirky Bob the Seer, awesome Chelsie the Shade and obnoxious Justin the Knight/Champion – each and every one of them are great in their own special way and their characters were much more fully explored in this book.
It was hard to put this book down once it really started to get down to business around one-third in. There were so many revelations and cool action set-pieces replete with lots and lots of awesome magic. And it was all wrapped up in an amazing climax which was then followed by an earth-shattering event. I am definitely hooked on this series now.
