CITY OF GLASS

The cliffs rose higher around the lake as they progressed, pocked with spots of darkness, like splashes of black paint. As Clary looked more closely, she realized they were caves in the rock. Some looked like they went very deep, twisting away into darkness. She imagined bats and creepy-crawling things hiding in the blackness, and shivered.

At last a narrow path cutting through the cliffs led them to a wide road lined with crushed stones. The lake curved away behind them, indigo in the late afternoon sunlight. The road cut through a flat grassy plain that rose to rolling hills in the distance. Clary’s heart sank; the city was nowhere in sight.

Luke was staring toward the hills with a look of intense dismay on his face. “We’re farther than I thought. It’s been such a long time….”

“Maybe if we found a bigger road,” Clary suggested, “we could hitchhike, or get a ride to the city, or—”

“Clary. There are no cars in Idris.” Seeing her shocked expression, Luke laughed without much amusement. “The wards foul up the machinery. Most technology doesn’t work here—mobile phones, computers, the like. Alicante itself is lit—and powered—mostly by witchlight.”

“Oh,” Clary said in a small voice. “Well—about how far from the city are we?”

“Far enough.” Without looking at her, Luke raked both his hands back through his short hair. “There’s something I’d better tell you.”

Clary tensed. All she’d wanted before was for Luke to talk to her; now she didn’t want it anymore. “It’s all right—”

“Did you notice,” Luke said, “that there weren’t any boats on Lake Lyn—no docks—nothing that might suggest the lake is used in any way by the people of Idris?”

“I just thought that was because it was so remote.”

“It’s not that remote. A few hours from Alicante on foot. The fact is, the lake—” Luke broke off and sighed. “Did you ever notice the pattern on the library floor at the Institute in New York?”

Clary blinked. “I did, but I couldn’t figure out what it was.”

“It was an angel rising out of a lake, holding a cup and a sword. It’s a repeating motif in Nephilim decorations. The legend is that the Angel Raziel rose out of Lake Lyn when he first appeared to Jonathan Shadowhunter, the first of the Nephilim, and gave him the Mortal Instruments. Ever since then the lake has been—”

“Sacred?” Clary suggested.

“Cursed,” Luke said. “The water of the lake is in some way poisonous to Shadowhunters. It won’t hurt Downworlders—the Fair Folk call it the Mirror of Dreams, and they drink its water because they claim it gives them true visions. But for a Shadowhunter to drink the water is very dangerous. It causes hallucinations, fever—it can drive a person to madness.”

Clary felt cold all over. “That’s why you tried to make me spit the water out.”

Luke nodded. “And why I wanted you to find your stele. With a healing rune, we could stave off the water’s effects. Without it, we need to get you to Alicante as quickly as possible. There are medicines, herbs, that will help, and I know someone who will almost certainly have them.”

“The Lightwoods?”

“Not the Lightwoods.” Luke’s voice was firm. “Someone else. Someone I know.”

“Who?”

He shook his head. “Let’s just pray this person hasn’t moved away in the last fifteen years.”

“But I thought you said it was against the Law for Downworlders to come into Alicante without permission.”

His answering smile was a reminder of the Luke who had caught her when she’d fallen off the jungle gym as a child, the Luke who had always protected her. “Some laws were meant to be broken.”

The Penhallows’ house reminded Simon of the Institute—it had that same sense of belonging somehow to another era. The halls and stairways were narrow, made of stone and dark wood, and the windows were tall and thin, giving out onto views of the city. There was a distinctly Asian feel to the decorations: a shoji screen stood on the first-floor landing, and there were lacquer-flowered tall Chinese vases on the windowsills. There were also a number of silk-screen prints on the walls, showing what must have been scenes from Shadowhunter mythology, but with an Eastern feel to them—warlords wielding glowing seraph blades were prominently featured, alongside colorful dragonlike creatures and slithering, pop-eyed demons.

“Mrs. Penhallow—Jia—used to run the Beijing Institute. She splits her time between here and the Forbidden City,” Isabelle said as Simon paused to examine a print. “And the Penhallows are an old family. Wealthy.”

“I can tell,” Simon muttered, looking up at the chandeliers, dripping cut-glass crystals like teardrops.
