Undercover Wolf

Private investigator Quinn Parran plans to infiltrate Alpha Force, a special military unit made up of shape-shifters, so he can use the team's new elixir to sharpen his own shifting powers. Working alongside Sergeant Kristine Norwood, he finds that each transformation session stirs up a feeling far more unpredictable than any obstacle he has faced before: an intense, instinctive attraction.

The plot takes a sharper turn when Quinn's brother disappears during his honeymoon and becomes the prime suspect in a murder. Quinn and Kristine must team up to uncover what happened. Posing as newlyweds, they go deep undercover, and Kristine starts to enjoy the pretense more than she expects. She is drawn to Quinn but has no intention of getting involved with a shape-shifter, until the mission grows more perilous and she has to set her doubts aside and trust him completely.
