I read this book a couple of weeks ago. I have to admit that I couldn't wait to get my hands on this book, because I like Lynn Flewelling's fantasy books.
At first I was a bit afraid that the quality of this book might be bad, because long fantasy series have a tendency to become boring after the first books. Fortunately this book was quite good and the story was interesting.
I must say that Lynn Flewelling is a talented fantasy writer, who knows how to write good and entertaining adult fantasy. In my opinion this book is entertainment and it's not meant to be taken seriously.
If you've read the previous Nightunner books and liked them, you should read Shadows Return, because it continues the story of Alec and Seregil.
