I found this book very intriguing. I am obsessed with Nalini Singh's Hunter's Guild series so I wanted to read more of her books and this was the one I chose. 
 I loved the concept of the Psy and their "emotionless" existence. Especially since everything we do is due to our emotions. Sascha was interesting to read about and to see as she struggled to hide the emotions she experiences, especially around Lucas. Lucas too was a pretty straightforward unapologetic guy. He was a force of nature and tried his hardest to make Sascha show her feelings.
