Omar Khan, former undercover agent for the DEA and current special operative for Potomac Private Services, fears nothing—nothing that is except for a small, bespectacled half-French former CIA analyst who holds his heart in the palm of her hands.

Data geek Marielle Moreau understands numbers. Patterns, statistics, algorithms—these make sense to her. People, not so much. One person in particular, her coworker and crush Omar Khan, is incomprehensible. Omar runs hot and cold with her.

But when Potomac Private Services takes on a high-stakes case, Omar and Marielle are thrust out of the friend zone and into the danger zone together. Assigned to infiltrate a heavily guarded yacht at sea and retrieve sensitive data, Marielle and Omar's cover is that of a couple in love. Will they succeed in their mission? And will their fake relationship turn into something more?
