They were walking up Queen’s Gate toward Kensington Road, the clatter of omnibus traffic all around them. Cordelia imagined James wandering off into the crowd, where surely he would find something more interesting to do, or perhaps be kidnapped by a beautiful heiress who would fall in love with him instantly. These sort of things happened in London.

“I will walk ten paces behind you like a train-bearer,” said James. “But I must keep you within sight, otherwise Mother will kill me, and then I will miss tomorrow’s ball and Matthew will kill me, and I will be dead twice.”

Cordelia smiled, but James was already dropping back as promised. He ambled along behind them, giving the girls space to talk; Cordelia tried to hide her disappointment at the lack of his presence. She lived in London now, after all, and sightings of James were no longer rare glimpses but would hopefully become part of her everyday life.

She glanced back at him; he had already taken out a book and was reading it while walking and whistling under his breath.

“What ball did he mean?” she asked, turning to Lucie. They passed under the black wrought-iron gates of Kensington Park and into leafy shade. The public garden was full of nannies pushing babies in prams and young couples walking together under the trees. Two little girls were making daisy chains, and a boy in a blue sailor suit was running along with a hoop, shrieking with laughter. He ran to a tall man, who picked him up and swung him into the air as he laughed. Cordelia squeezed her eyes shut for a moment, thinking of her own father, of the way he had tossed her into the air when she was very small, making her laugh and laugh even as he caught her on her way down.

“The one tomorrow night,” Lucie said, linking her arm with Cordelia’s. “We’re throwing it to welcome you to London. All the Enclave will be there, and there will be dancing, and Mother will have a chance to show off the new ballroom. And I will have a chance to show off you.”

Cordelia felt a chill go over her—part excitement, part fear. The Enclave was the official name for the Shadowhunters of London: every city had an Enclave, who answered to their local Institute as well as the superior authority of the Clave and the Consul. She knew it was foolish, but the thought of so many people prickled her skin with anxiety. The life she had lived with her family—constantly traveling save when they were at Cirenworth in Devon—had been devoid of crowds.

And yet this was what she had to do—what they had all come to London to do. She thought of her mother.

It was not a ball, she told herself. It was the first skirmish in a war.
