High-flying executive Celia Scott is on her way to Tokyo to accept a prestigious award heavy with emotional baggage. She'll make the trip, but she doesn't have to like it, and she certainly doesn't have to make nice with a stranger on a plane. Artist Lily Andersen is excited to finally meet her online crush, the only person in the world who truly gets her. She just needs to survive the eleven-hour flight from London to Japan with a testy seatmate who by turns annoys and fascinates her. Fate, upgrades, and a troupe of travelling clowns bring them together for a journey memorable for all the wrong reasons.
