The Knight by Theresa Beachman

Logic is her life, but love doesn’t follow rules.

Neuroengineer, Freya Jonsdottir, thought she’d landed her dream job—archiving classified research at a top-secret lab in Hellisheidi, Iceland. But when the high-risk research is stolen, her dream turns into a nightmare. Now with ruthless assailants determined to unlock the secrets on her encrypted laptop, Freya’s only hope lies with the most infuriating man in the northern hemisphere.
Abe Knight, a rugged former SEAL with a killer smile, puts his special talents to good use as an elite operative for Guardsmen Security. His life is just how he likes it—a challenging career, good friends and zero attachments. But when he’s assigned to protect the brilliant yet headstrong scientist, trouble is inevitable.
Thrust into the treacherous underworld of Raptor Industries, Abe and Freya must navigate a web of deception where allies can’t be trusted and enemies lurk in every shadow. Forced on the run, they race against time to outwit their relentless pursuers. And as the danger escalates, so does the electrifying attraction simmering between them.
With everything on the line, Freya and Abe must rely on each other to survive. But in a game this deadly, can they stay alive long enough to bring down the walls around each other’s hearts?
