" Do you remember when we stood together on Blackfriars Bridge?” he asked softly, and his eyes were like that night had been, all black and silver.
“Of course I remember.”
“It was the moment I first knew I loved you,” Jem said. “I will make you a promise. Every year, Tessa, on one day, I will meet you on that bridge. I will come from the Silent City and I will meet you, and we will be together, if only for an hour. But you must tell no one. "
