Clockwork Prince by Cassandra Clare Page A

nothing of the term from the Codex.
    Jem said, “When a Shadowhunter wishes to marry a mundane—”
    “But I thought that was forbidden?” Tessa asked, as the train slid into a tunnel. It was dark suddenly in their compartment, though she had the feeling nevertheless that Will was looking at her, that shivering sense that his gaze was on her somehow.
    “It is. Unless the Mortal Cup is used to turn that mundane into a Shadowhunter. It is not a common result, but it does happen. If the Shadowhunter in question applies to the Clave for an Ascension for their partner, the Clave is required to consider it for at least three months. Meanwhile, the mundane embarks on a course of study to learn about Shadowhunter culture—”
    Jem’s voice was drowned out by the train whistle as the locomotive emerged from the tunnel. Tessa looked at Will, but he was staring fixedly out the window, not looking at her at all. She must have imagined it.
    “It’s not a bad idea, I suppose,” said Tessa. “I do know rather a lot; I’ve finished nearly all of the Codex .”
    “It would seem reasonable that I brought you with me,” said Jem. “As a possible Ascender, you might want to learn about Institutes other than the one in London.” He turned to Will. “What do you think?”
    “It seems as fine an idea as any.” Will was still looking out the window; the countryside had grown less green, more stark. There were no villages visible, only long swathes of gray-green grass and outcroppings of black rock.
    “How many Institutes are there, other than the one in London?” Tessa asked.
    Jem ticked them off on his hands. “In Britain? London, York, one in Cornwall—near Tintagel—one in Cardiff, and one in Edinburgh. They’re all smaller, though, and report to the London Institute, which in turn reports to Idris.”
    “Gideon Lightwood said he was at the Institute in Madrid. What on earth was he doing there?”
    “Faffing about, most likely,” said Will.
    “Once we finish our training, at eighteen,” said Jem, as if Will hadn’t spoken, “we’re encouraged to travel, to spend time at other Institutes, to experience something of Shadowhunter culture in new places. There are always different techniques, local tricks to be learned. Gideon was away for only a few months. If Benedict called him back so soon, he must think that his acquisition of the Institute is assured.” Jem looked troubled.
    “But he’s wrong,” Tessa said firmly, and when the troubled look didn’t leave Jem’s gray eyes, she cast about for something to change the subject. “Where is the Institute in New York?”
    “We haven’t memorized all their addresses, Tessa.” There was something in Will’s voice, a dangerous undercurrent. Jem looked at him narrowly, and said:
    “Is everything all right?”
    Will took his hat off and laid it on the seat next to him. He looked at them both steadily for a moment, his gaze level. He was beautiful to look at as always, Tessa thought, but there seemed something gray about him, almost faded. For someone who so often seemed to burn very brightly, that light in him seemed exhausted now, as if he had been rolling a rock up a hill like Sisyphus. “Too much to drink last night,” he said finally.
    Really, why do you bother, Will? Don’t you realize we both know you’re lying? Tessa almost said, but one look at Jem stopped her. His gaze as he regarded Will was worried—very worried indeed, though Tessa knew he did not believe Will about the drinking, any more than she did. But, “Well,” was all he said, lightly, “if only there were a Rune of Sobriety.”
    “Yes.” Will looked back at him, and the strain in his expression relaxed slightly. “If we might return to discussing your plan, James. It’s a good one, save one thing.” He leaned forward. “If she is meant to be affianced to you, Tessa will need a ring.”
    “I had thought of that,” said Jem, startling Tessa, who had imagined he had come up with
