A Priya and Barrons are getting intimate, learning each other in the beginning of the book. 
 Barrons is Barrons because he told her that it is his name. 
 The Priya is Mac because he told her that it is her name. 
 If you don't know what a priya is, you have started reading the series from the wrong book. Start again, trying another book first. 
 When Mac and Barrons are having sex together finally, it will be fantastic but it will also be bitter. Because it is not a matter of a mutual decision or because they realize that they love each other. It will be mainly a matter of survival. 
 This is the book where all the major players of the series are finally brought together. 
 All the enemies, friends and lovers (hard to tell who is what still): Barrons and his team (yes, there are a lot like him), Ryodan, Mac, V'lane, Derek O'Bannion, Christian MacKeltar, Rowena, Dani, Kat, the three Unseelie Princes, a strange monster who will have a strange ending and who may be someone we know. 
 This is a fast paced, excellent written, smoothly executed, originality oozed book. Everything and everyone matter in this book. 
 Most of the scenes are worth mentioning. I am picking the most heartbreaking one: 
 He touches my face. 
 There is something different in his touch. It feels like he's saying good-bye, and I know a moment of panic. 
 But my dream sky darkens and sleep's moon fills the horizon. 
 "Don't leave me." I thrash in the sheets. 
 "I'm not, Mac." 
 I know I am dreaming then, because dreams are home to the absurd and what he says next is beyond absurd. 
 "You're leaving me, Rainbow Girl."
