Plot: This book had much more to it than the first book in this series. There were several plot twists and unexpected turns throughout the story. It continues perfectly where the first book leaves off, and ends at a place where you want to immediately read the next book.
Characters: The character development wasn't as good as the first book. Since you are already familiar with most of the characters, there was not a lot to be mentioned about the characters themselves, only plot advancement. I don't necessarily think it's a bad thing though, since this is the second book, you already know about the characters what you need to.
Themes: This book really deals with good versus evil and the struggle to sometimes know which side is in fact good and which evil. Thomas is forced to try to understand those of the strange symbol" while at the same time not really knowing anything about the Immortals.
Emotion: As with the first book, I did not think that there was much depth to the emotion. Towards the end, you read of Katherine's emotion's towards being bandaged and not being able to allow Thomas to see her for who she really is. I don't feel, however, that this is enough to compensate for the entire book.
Overall: I really enjoyed reading this book. It was another quick read that kept me wanting to know what was going to happen to Thomas and to Magnus and what each side of these opposing societies was going to do next. The last words in the book leave you in anticipation for what is to come in the next books.
