I love this author's style. It's refreshing. The plot is great, the characters are tough AND sensitive fighters, the ladies in the story are anything but weak, and the sensuality is intense - typical Voinov. 
 This said, what I liked the most was the Morphs, these creatures who can read your lines, your patterns (who you are under your skin), read your thoughts and take your appearance. They regenerate too, so their injuries don't last. We don't know if they are male of female underneath their physical body, they just ARE. And because they can morph, they can incarnate whoever exists under their skin. Human beings fear them for their unusual skills and all kind of horror stories are told about them. But is it true? 
 Kyle will find out. 
 I loved this book.
