I was mildly surprised to see that this book took a different turn in how the main male and female came together, and I found it renewing my interest in the book as it became almost unpredictable again. I think that is the problem with any long series, predictability. The story was written fairly well. However, the story left me asking questions and questioning the soundness of the plot.
My reason for questioning the plot was that in the end when Orpheus saves his brother, the author says he needs to orb to save his brother but never really shows why or how he needs the orb to save his brother. It left me wondering. Then, once his brother is saved the author mentions the marks being back on the brother where they belong but then later Orpheus still wears them.
Over all I would rate this book a 3 out of 5 stars, I am a little unsure if I would recommend the book itself though, as a series I would.
