Undercover Wolf

Alpha Force Book 4
April 10, 2025

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.

originally published by Harlequin Nocturne in 2013

Reviews

"UNDERCOVER WOLF is nonstop action with a number of twists and turns that has the reader still getting answers to questions until the very last page. I enjoyed the way the trust built up between the main characters through the storyline until the end when that trust is needed it's there. Ms. Johnston has a winner on her hands with this installment of the Alpha Force series." -- Annetta Sweetko, FreshFiction

"In this exciting continuation of the Alpha Force storyline, Quinn is a likable character, both sexy and strong, and Kristine’s clever moves in crisis show an intelligence that will appeal to readers." -- Alexandra Kay, RT Book Reviews
