Joan Blakely had an unconventional childhood: the daughter of a globe-trotting supermodel and a world-famous artist. Her artist father died on 9/11, and Joan—an art historian by training—has spent more than a decade maintaining his legacy. Life in the art world is beginning to wear on her—and then one fateful afternoon her husband drops a bombshell: he’s fathered twins with another woman. Furious but secretly pleased to have a reason to blow up her life, Joan impulsively decides to get out of town, booking a last-minute trip to Paris as an art courier: the person museums hire to fly valuable works of art to potential clients, discreetly stowed in their carry-on luggage. Sipping her champagne in business-class, she chats up her seatmate, Nate, a good-looking tech nerd who invites her to dinner in Paris. He doesn’t know she’s carrying drawings worth hundreds of thousands of dollars. But after a romantic dinner and an even more romantic night together, Joan wakes up next to her new lover to discover the drawings gone. Even more shocking is what’s been left in their place: a sketch from her father’s journals, which she thought had been lost when he died on 9/11, and a poem that reads like a treasure hunt. With Nate as a sidekick, Joan will follow the clues all over Paris—from its grand cathedrals to the romantic bistros to the twisty side streets of Montmartre—hoping to recover the lost art, and her own sense of adventure. What she finds is even better than she’d expected.
