In If You Were Here by Alafair Burke, a young pickpocket is pulled from the tracks of a subway station seconds before an oncoming train's arrival. When a video of the incident briefly emerges it unlocks a mystery that goes back over a decade.
When McKenna Jordan, a magazine journalist investigating the story of the heroic and unidentified woman, finds the video footage, she thinks she recognizes her as Susan Hauptmann. But Susan disappeared without a trace ten years earlier, having just introduced McKenna to her future husband, Patrick.
