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.

Second-generation spy Yardley Whitmer, code name “the Unicorn,” can do no wrong. With her combination of debutante-style charm and expert spycraft, she’s become an instant legend in the field. If only finally moving out of her girlfriend’s home were as easy as rappelling off the Eiffel Tower. But living a full-time cover story has slowly eroded her relationship with KC until there’s nothing left but lies.

KC “Tabasco” Nolan, hacker extraordinaire, can crack anything—except the code 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 are Unicorn and Tabasco, and they’ve both been working with the agency for years. To salvage the mission, they’re compelled to 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 Plan A and fight through the betrayal and secrets to fall in love with each other’s true selves?
