Slave to Sensation is an alternative history paranormal, set in the year 2079 on an Earth populated by three races: the Psy - emotionless and cold, the shapeshifting Changelings who rely on their animal instincts, and humans.
From the moment that Lucas Hunter (Changeling) and Sascha Duncan (Psy) meet there is a chemistry between them that fairly leaps off the page. This causes conflict as Lucas is a creature of instinct and sensation, whilst Sascha must maintain a facade of logic and efficiency at all costs.
Although it is the love story between Lucas and Sascha that is the driving force behind the narrative. The reason this book works so well is because you can immerse yourself in the world that Nalini Singh has created. The dynamics of both pack (Changeling) and Psy life are well-explained and the book is populated with interesting characters that give the story an added depth. And at the same time leave you wanting to know more about them. :)
One of the things I like is that it's made clear that both species are equally capable of brutality. Psy who don't conform to the acceptable standards of the Silence live with the constant threat of rehabilitation (mind-wiping) at the Center. Whilst the Changelings live under a territorial law that can erupt into violence. However, the reader does come down on the side of the Changeling way of life with its emphasis on family and pack.
There are one or two slips, but when the standard of storytelling is this high, they are easily forgiven. This is one of the best paranormals I've read and I would rank it with J.R.Ward's Black Dagger Brotherhood as one of my favourite series. Visions of Heat (Book 2) is released in March 2007
