Clockwork Princess

little but his memory clear.
    The dagger was there among the roots of the trees, which had grown around the hilt. She had had to cut some of them away, and dig at the dirt and rocks with a trowel, before she could free it. Jem’s blade, stained dark now with weather and the passage of time.
    She had brought it to Jem that year on the bridge. It was 1937 and the Blitz had not yet come to level the buildings around Saint Paul’s, to strafe the sky with fire and burn the walls of the city Tessa loved. Still, there was a shadow over the world, the hint of a coming darkness.
    “They kill each other and kill each other, and we can do nothing,” Tessa had said, her hands on the worn stone of the bridge parapet. She was thinking of the Great War, of the spendthrift waste of life. Not a Shadowhunter war, but out of blood and war were demons born, and it was the responsibility of the Nephilim to keep demons from wreaking even greater destruction.
    We cannot save them from themselves
, Jem had replied. He wore his hood up, but the wind blew it back, showing her the edge of his scarred cheek.
    “There is something coming. A horror Mortmain could only have imagined. I feel it in my bones.”
    No one can rid the world of all evil, Tessa
.
    And when she drew his dagger, wrapped in silk, though still dirty and stained with earth and Will’s blood, from the pocket of her coat and gave it to him, he bent his head and held it to him, hunching his shoulders over it, as if protecting a wound to his heart.
    “Will wanted you to see it,” she said. “I know you cannot take it with you.”
    Keep it for me. There may come a day
.
    She did not ask him what he meant, but she kept it. Kept it when she left England, the white cliffs of Dover retreating like clouds in the distance as she crossed the Channel. In Paris she found Magnus, who was living in a garret apartment and painting, an occupation for which he had no aptitude whatsoever. He let her sleep on a mattress by the window, and in the night, when she woke up screaming for Will, he came and put his arms around her, smelling of turpentine.
    “The first one is always the hardest,” he said.
    “The first?”
    “The first one you love who dies,” he said. “It gets easier, after.”
    When the war came to Paris, they went to New York together, and Magnus reintroduced her to the city she had been born in—a busy, bright, buzzing metropolis she barely recognized, where motorcars crowded the streets like ants, and trains whizzed by on elevated platforms. She did not see Jem that year, because the Luftwaffe was strafing London with fire and he had deemed it too dangerous to meet, but in the years after—
    “Tessa?”
    Her heart stopped.
    A great wave of lurching dizziness passed over her, and for a moment she wondered if she were going mad, if after so many years the past and present had blended within her memories until she could no longer tell the difference. For the voice she heard was not the soft, silent voice-within-her-mind of Brother Zachariah. The voice that had echoed in her head once a year for the past one hundred and thirty years.
    This was a voice that drew out memories stretched thin by years of recollection, like paper unfolded and refolded too many times. A voice that brought back, like a wave, the memory of another time on this bridge, a night so long ago, everything black and silver and the river rushing away under her feet …
    Her heart was pounding so hard, she felt as if it might break through her rib cage. Slowly she turned, away from the balustrade. And stared.
    He stood on the pavement in front of her, smiling shyly, hands in the pockets of a pair of very modern jeans. He wore a blue cotton jumper pushed up to the elbows. Faint white scars decorated his forearms like lacework. She could see the shape of the rune of Quietude, which had been so black and strong against his skin, faded now to a faint imprint of silver.
    “Jem?” she whispered, realizing why she had not seen him when she’d been searching the crowd for him. She had been looking for Brother Zachariah, wrapped in his parchment-white robe, moving, unseen, through the throng of Londoners. But this was not Brother Zachariah.
    This was Jem.
    She couldn’t tear her gaze away from him. She had always thought Jem was beautiful. He was no less beautiful to her now. Once he had had silver-white hair and eyes like gray skies. This Jem had raven-black hair, curling slightly in the humid air, and
