Off the Grid by Kay Marie

One part Pride and Prejudice.
One part Romancing the Stone.
All the feels.
Agent Leo Alvarez is on his way to Hawaii when his partner calls in a favor–the mob is after a pastry chef in NYC, and he’s the only one who can get to her in time. With his dreams of Mai Tais and sandy shores ruined, Leo rushes to her rescue. But when he arrives at her apartment, he’s greeted by an upturned nose and an icy blue stare. This damsel in distress doesn’t need saving. Good thing he’s a retired marine who never backs down without a fight.
After a childhood racked by scandal, McKenzie Harper has learned to loathe surprises. So when a strange man knocks on her door, interrupting her morning routine, she has no choice but to politely shut it in his face–no matter how deeply his hazel eyes might pierce. She has places to go, pastries to bake, and promotions to secure. Or she did, until three masked men kidnap her and throw her into the back of a van… Suddenly, that white knight doesn’t seem so scary.
He’s a cocky Fed with a killer smile. She’s an uptown beauty with a biting tongue. If they want to survive, they’ll have to learn to work together–assuming they don’t kill each other first.
