He headed back toward them with Cristina at his side. The tips of his pointed ears peeked through the loops of his light hair, but he was glamoured so that mundanes wouldn’t see them. Mark was half-faerie, and his Downworlder blood showed itself in the delicacy of his features, the tips of his ears, and the angularity of his eyes and cheekbones.

“So it’s a squid demon?” Emma said, mostly just to have something to say to fill the silence between her and Julian. There were a lot of silences between her and Julian these days. It had only been two weeks since everything had changed, but she felt the difference profoundly, in her bones. She felt his distance, though he had never been anything but scrupulously polite and kind ever since she had told him about her and Mark.

“Apparently,” Julian said. Mark and Cristina had come into earshot; Cristina was finishing her caramel corn and looking sadly into the bag as if hoping more would appear. Emma could relate. Mark, meanwhile, was gazing down at his prize. “It climbs up the side of the pier and snatches people—mostly kids, anyone leaning over the side taking a picture at night. It’s been getting braver, though. Apparently someone spotted it inside the game area near the table hockey—is that a goldfish?”

Mark held up his plastic bag. Inside it, a small orange fish swam around in a circle. “This is the best patrol we’ve ever done,” he said. “I have never been awarded a fish before.”

Emma sighed inwardly. Mark had spent the past few years of his life with the Wild Hunt, the most anarchic and feral of all faeries. They rode across the sky on all manner of enchanted beings—motorcycles, horses, deer, massive snarling dogs—and scavenged battlefields, taking valuables from the bodies of the dead and giving them in tribute to the Faerie Courts.

He was adjusting well to being back among his Shadowhunter family, but there were still times when ordinary life seemed to take him by surprise. He noticed now that everyone was looking at him with raised eyebrows. He looked alarmed and placed a tentative arm around Emma’s shoulders, holding out the bag in the other hand.

“I have won for you a fish, my fair one,” he said, and kissed her on the cheek.

It was a sweet kiss, gentle and soft, and Mark smelled like he always did: like cold outside air and green growing things. And it made absolute sense, Emma thought, for Mark to assume that everyone was startled because they were waiting for him to give her his prize. She was, after all, his girlfriend.

She exchanged a worried glance with Cristina, whose dark eyes had gotten very large. Julian looked as if he were about to throw up blood. It was only a brief look before he schooled his features back into indifference, but Emma drew away from Mark, smiling at him apologetically.

“I couldn’t keep a fish alive,” she said. “I kill plants just by looking at them.”

“I suspect I would have the same problem,” Mark said, eyeing the fish. “It is too bad—I was going to name it Magnus, because it has sparkly scales.”

At that, Cristina giggled. Magnus Bane was the High Warlock of Brooklyn, and he had a penchant for glitter.

“I suppose I had better let him go free,” Mark said. Before anyone could say anything, he made his way to the railing of the pier and emptied the bag, fish and all, into the sea.

“Does anyone want to tell him that goldfish are freshwater fish and can’t survive in the ocean?” said Julian quietly.

“Not really,” said Cristina.

“Did he just kill Magnus?” Emma asked, but before Julian could answer, Mark whirled around.

All humor had gone from his expression. “I just saw something scuttle up one of the pilings below the pier. Something very much not human.”

Emma felt a faint shiver pass over her skin. The demons who made the ocean their habitation were rarely seen on land. Sometimes she had nightmares where the ocean turned itself inside out and vomited its contents onto the beach: spiny, tentacled, slimy, blackened things half-crushed by the weight of water.

Within seconds, each of the Shadowhunters had a weapon in hand—Emma was clutching her sword, Cortana, a golden blade given to her by her parents. Julian held a seraph blade, and Cristina her butterfly knife.

“Which way did it go?” Julian asked.

“Toward the end of the pier,” said Mark; he alone had not reached for a weapon, but Emma knew how fast he was. His nickname in the Wild Hunt had been elf-shot, for he was swift and accurate with a bow and arrow or a thrown blade. “Toward the amusement park.”

“I’ll go that way,” Emma said. “Try to drive it off the edge of the pier—Mark, Cristina, you go down under, catch it if it tries to crawl back into the water.”

They barely had time to nod, and Emma was off and running. The wind tugged at her braided hair as she wove through the crowd toward the lighted park at the pier’s end. Cortana felt warm and solid in her hand, and her feet flew over the sea-warped wooden slats. She felt free, her worries cast aside, everything in her mind and body focused on the task at hand.

She could hear footsteps beside her. She didn’t need to look to know it was Jules. His footsteps had been beside hers for all the years she had been a fighting Shadowhunter. His blood had been spilled when hers was. He had saved her life and she had saved his. He was part of her warrior self.

“There,” she heard him say, but she’d already seen it: a dark, humped shape clambering up the support structure of the Ferris wheel. The carriages continued to rotate around it, the passengers shrieking in delight, unaware.

Emma hit the line for the wheel and started shoving her way through it. She and Julian had put glamour runes on before they’d gotten to the pier, and they were invisible to mundane eyes. That didn’t mean they couldn’t make their presence felt, though. Mundanes in line swore and yelled as she stomped on feet and elbowed her way to the front.

A carriage was just swinging down, a couple—a girl eating purple cotton candy and her black-clad, lanky boyfriend—about to climb in. Glancing up, Emma saw a flicker as the Teuthida demon slithered around the top of the wheel support. Swearing, Emma pushed past the couple, nearly knocking them aside, and leaped into the carriage. It was octagonal, a bench running around the inside, with plenty of room to stand. She heard yells of surprise as the carriage rose, lifting her away from the scene of chaos she’d created below, the couple who’d been about to board the wheel yelling at the ticket taker, and the people in line behind them yelling at each other.

The carriage rocked under her feet as Julian landed beside her, setting it to swinging. He craned his head up. “Do you see it?”

Emma squinted. She had seen the demon, she was sure of that, but it seemed to have vanished. From this angle, the Ferris wheel was a mess of bright lights, spinning spokes, and white-painted iron bars. The two carriages below her and Julian were empty of people; the line must still be sorting itself out.

Good, Emma thought. The fewer people who got on the wheel, the better.

“Stop.” She felt Julian’s hand on her arm, turning her around. Her whole body tensed. “Runes,” he said shortly, and she realized he was holding his stele in his free hand.

Their carriage was still rising. Emma could see the beach below, the dark water spilling up onto the sand, the hills of Palisades Park rising vertically above the highway, crowned with a fringe of trees and greenery.
