Slave to Sensation- Nalini Singh (book 1)

Dive into a world torn apart by a powerful race with phenomenal powers of the mind—and none of the heart…
In a world that denies emotions, where the ruling Psy punish any sign of desire, Sascha Duncan must conceal the feelings that brand her as flawed. To reveal them would be to sentence herself to the horror of “rehabilitation”— the complete psychic erasure of everything she ever was….
Both human and animal, Lucas Hunter is a Changeling hungry for the very sensations the Psy disdain. After centuries of uneasy co-existence, these two races are now on the verge of war over the brutal murders of several Changeling women. Lucas is determined to find the Psy killer who butchered his packmate, and Sascha is his ticket into their closely guarded society. But he soon discovers that this ice-cold Psy is very capable of passion—and that the animal in him is fascinated by her. Caught between their conflicting worlds, Lucas and Sascha must remain bound to their identities—or sacrifice everything for a taste of darkest temptation…
The Psy are a race that adopted to Silence, where emotions are denied and any sign of desire or feeling is punishable by "rehabilitation" - the complete psychic erasure of the mind.

He is convinced that is a Psy, although the Psy claim to have to violence within their race. Lucas devises a plan to partner with the Psy on a construction venture and that is when he meets Sascha. He senses that there is something different about Sascha and believes that she is his ticket in to the Psy society. However, he soon discovers that his animal is fascinated by her and discovers that maybe Sascha is very capable of passion and feeling. The two of them find themselves in a conflicting situation and learn that sacrifices must be made.
Very good book. I'd give it a Rating of 4, only because there could have been some more "lovin" in it, but the story-line is great.... Thanks Georgia (Guest Author)
