Undercover Wolf

Mystery, intrigue, and romance abound in this paranormal series that follows members of the Alpha Force—a secret branch of the military mostly composed of shapeshifters. An essential part of the U.S. defense forces in the United States, this undercover, elite, supernatural team uses its power to help investigate any major and mysterious crimes that cross their path, all while battling—or finally giving into—their passions.
P.I. Quinn Parran's mission is to join Alpha Force, a unique military team of shape-shifters, and use their new elixir to enhance his shape-shifting abilities. But with the aid of Sergeant Kristine Norwood, each experiment sparks something more volatile than any challenge he's ever encountered: a primal passion. When Quinn's brother vanishes on his honeymoon and is suspected of murder, Quinn ends up joining forces with Kristine to investigate the truth.
Kristine has no choice but to go deep undercover as Quinn's newlywed wife, and it's not long before she finds herself enjoying the charade a little too much. She's attracted to Quinn, but she isn't about to get involved with a shape-shifter. Until their quest becomes more dangerous, and Kristine is forced to put aside her doubts and place her full trust in Quinn—with her heart on the line just as surely as the success of their mission.
