There's a fine line between pain and pleasure, and it's so very easy to cross. As Rose Wintersong awakens to her own sexual nature, the darkness growing inside her threatens to consume the man she loves. Each touch puts his very soul at risk. But she thinks she's found a way to control it. Pain. Derek O'Conner has always exercised control over his own powers, but being with Rose unleashes the beast within and challenges him to embrace his own wild magic. When they embark on a sexual path that leads them down a deadly road of pain and pleasure, Derek finds he is unable to stay away from the woman whose family has tried to destroy his. But one night, one touch, could destroy them both and give Rose's family what they need to end the O'Conner shifter line forever.
