Now he is bitter and striped of his power recently bought by the callous and cruel Prince Aleksander heir to the Derzhi Empire.

I loved this book and could not put it down. The growth of the characters of Aleksander and Seyonne the changes in the way they view the world are so intriguing. I immediately ordered the second book when I finished.
