How do you defeat an enemy that's inside your head?
Dragging an innocent into his war was never a part of the plan.
When Heath Kavanaugh agreed to a covert mission at a local university to discover who is stealing classified research, he knew it would be dangerous. Being sent in as a janitor is the perfect cover—nobody spares him a second glance.
Except for Lyn, the linguistics doctoral student with a shy smile and luscious curves. Some might say she’s heavy, but he just sees gorgeous—brilliant and kind to boot. Keeping her at arm’s length, and out of danger’s path, is killing him.
But when peril finds her anyway, arm’s length isn’t an option anymore. And it’s going to take every skill he’s ever learned as part of Linear Tactical to keep them both alive.
