"As I followed Margo's directions through the maze of one-way streets, we saw a few people sleeping on the sidewalk or sitting on benches, but nobody was moving. Margo rolled down the window, and I felt the thick air blow across my face, warmer than night ought to be. I glanced over and saw strands of her hair blowing all around her face. Even though I could see her there, I felt entirely alone among these big and empty buildings, like I'd survived the apocalypse and the world had been given to me, this whole and amazing and endless world, mine for the exploring."
