Ms. and Ms. Smith meets The Pairing in this heart-racing romance of secrets, spies, and steam.

A few rules for the international superspy:

(1) Never blow your cover.

(2) Never accept the first plan.

(3) Never fall for anyone at the agency. Especially if she’s your ex-girlfriend.

Yardley Whitmer, code name “the Unicorn,” can do no wrong. She’s honed her spycraft and become an instant legend in the field. If only breaking up with her girlfriend were as easy as rappelling off the Eiffel Tower. Living a full-time cover story has slowly eroded her relationship until there’s nothing left but lies.

KC “Tabasco” Nolan, hacker extraordinaire, can crack any code—except the one that would tell her the right moment to confess her secret job to Yardley. Now it’s too late, and she’s in danger of losing the best chance at love she’s ever had.

When an undercover shakedown goes wrong, Yardley and KC discover the unbelievable truth—that they’ve both been working at the agency for years. To salvage the mission, they partner up and fly across oceans, race through winding European streets, and give in to inconvenient passion while hiding in an ambassador’s linen closet. But can they throw away their rules and fight through their secrets to fall in love with each other’s true selves?
