The Lola Quartet was playing “Bei Mir Bist Du Schön” for the second time and a pretty girl named Taylor from Choir was singing in her best dusky lounge voice. They were all in love with the music and also a little in love with Taylor, or at least Gavin was and he imagined that everyone around him was caught up in the same dream. And then he caught a flash of white out of the corner of his eye and that was the paper airplane, arcing down through the air to land at his feet. He knew only one person with aim that perfect. He looked up and saw her, Anna standing just beyond the dancers at the edge of the light, and he half-smiled around the mouthpiece at her but she didn’t smile back. There was something urgent in the way she looked at him.
— Emily St. John Mandel, from The Lola Quartet
