Christopher is the sort of guy that no one notices, yet when Air catches sight of him making intricate paper birds in the airport, she can't look away. But their worlds are about to collide in ways they never expected. Someone they love is on Flight 0217 from London Heathrow. And it's missing. Convinced that her brother was on a different flight, Air drives them hundreds of miles across the country, on a trip that will change their lives forever.

But how do you tell the person you're falling for that you might just be the reason their life has fallen apart?
