" Two kinds of people camped out in the New York Public Library so late at night. There were the scholars: Caffeine-addled college students. Obsessively meticulous PhD candidates. Ambitious academics angling for tenure.

And then there were the people who had nowhere else to go: People who sought solace in the comforting musk of old books and the quiet sound of other humans breathing, turning pages, and stretching in their creaky wooden chairs. People who wanted to know that they weren't alone while being left alone.

People like Echo. "
