I was enthralled the entire time I was reading this book! I have already read some of the short stories by Singh and knew about the mated pair Clay talks about (Zach and Annie), Annie being the first human to enter the pack in this series, but the full length story of a human and changeling romance was intriguing. 
 I loved that Singh wrote the story so that Clay and Talin were friends as children. They memories of their childhood are brutal and beautiful. It becomes clear from the beginning that Clay had found his mate and that their separation was the source of both of their pain. Not only does Singh create a wonderful story but she tosses in enough problems to make happily ever after a bit further away than one would expect. 
 Because of the supposed death of Talin and Clay's incarceration because of the killing of Talin's foster father you realize that Clay's animal nature is more volatile than other of the DarkRiver Pack. It is when Talin walks back into his life that things start spinning out of control but it is her need for protection that helps him heal. Clay quickly because my favorite Changeling/Psy yet. 
 The Talin character endures far more than anyone should have to but through her pain as an abused child she sought solace in Clay. They were inseparable until Clay learned the truth about her situation and kills to protect a mate he doesn't realize he has at such a young age. While we discover something new about their separation, we also learn that in the intervening years Talin has spun emotionally out of control. She has shut down in aspects of her life that would have been nurtured and healed with Clay in her life. 
 The best part of this couple is they start realizing that all the pain they've endured is fixed when they accept that they are meant to be mated for life. But through all that they are fighting an evil Psy plot which involved the Psy's Forgotten and the children that Talin has deemed hers. The journey and adventure these characters set out on is wonderful and well worth the read. 
 I honestly wasn't sure I would like this series as much as I am. It isn't the most intellectual book in the world but it is a fantastic escape into the future and into fantasy.
