Overall this was a great book and an excellent continuation of the series. I love how Raisa's character is developing and I found Han's inner struggles especially interesting.
It does well furthering both Han and Raisa's story lines, but I felt the wider story was somewhat at a halt. There was considerably less action than The Demon King, and the plot seemed to flow nicely until they reached their destination. From there it slowed down.
If you liked The Demon King, chances are you will with this too. It can drag at times, but the writing is once again beautiful and captivating. I'm looking forward to continuing the series!
