Emma frowned. She found the whole business confusing, but one thing she was certain of—there was nothing Kieran wanted more than to be with Mark and Cristina.

“Cristina!” A voice echoed faintly from outside the Institute; Emma scrambled across the bed to the window and threw it open. A second later Cristina was beside her. They both poked their heads outside to see Diego and Jaime standing on the front lawn, waving their arms energetically. “Cristina! Come down!”

Cristina started to laugh, and for a moment, under her quiet sadness, Emma saw the girl she must have been in Mexico City when she was a child, tearing around with the Rosales brothers and getting into trouble.

She couldn’t help but smile. I wish I’d known you then, Tina. I hope we’ll be friends our whole lives.

But Cristina was smiling and Emma didn’t want to break her fragile good mood with wistfulness. “Come on,” she said, grabbing a pair of sandals. “Let’s go down to the beach.”

With help from Ragnor and Catarina, the sandy strip of coast below the Institute had been blocked off for their private use, the area encircled by glamoured signs claiming the beach was closed due to a terrible sand crab infestation.

Magnus had also thrown up muffling spells that quieted the sounds of traffic from the highway. Emma knew he hadn’t been involved in the weather, but it was almost as if he had: a perfect day, the sky blue and deep, the waves like blue satin threaded with gold.

Shadowhunters and Downworlders dotted the beach, all up and down the curve of golden sand encircled with rocks. Alec, tall and handsome in an ivory sweater and black pants, was helping Catarina and Ragnor set up tables of food. Emma noticed that his hands shook slightly as he set out plates and chopsticks. Magnus had summoned dumplings from all over the world—Chinese jiaozi, Japanese gyoza, Polish cheese pierogi, buttery Russian pelmeni, Korean mandu. Ragnor had provided bottles of ludicrously expensive wine from his favorite Argentinian vintner, as well as French sparkling water and apple juice for the kids. Catarina had created a fountain of Swiss chocolate, which had already attracted the attention of Max and Rafe. “Sandy fingers out of the chocolate,” Magnus was telling them. “Or I’ll turn you both into sea sponges.”

Cristina headed off down the beach with the Rosales brothers to catch up with Mark, who had been sitting alone on a hillock of sand, his eyes fixed on the middle distance. Emma bent to lace her sandal. When she straightened up, Julian had appeared, his jeans rolled to his knees and his bare feet sandy from playing at the water’s edge with Tavvy and Helen. He looked carefree in a way she had almost never seen him: His blue-green eyes sparkled like the sea glass at his wrist, and his smile was slow and easy as he came up to slide his arm around her waist. “You look gorgeous.”

“So do you,” she said, meaning it, and he laughed and kissed her. She marveled a little—Julian, who had always been so careful, was the one who didn’t care who knew about their relationship. She knew their family understood everything, that Jem had explained it to them in Alicante. But she always worried—would others wonder how long they’d been in love, how much it overlapped with their time of being parabatai?

No one seemed to care, though, and Julian least of all. He smiled whenever he saw her, caught her up and kissed her, held her hand proudly. He even seemed to enjoy the good-natured wailing of his siblings when they happened on Julian and Emma kissing in the hallways.

It was amazing not to have to be secret, not to hide. Emma wasn’t used to it yet, but she kissed Julian back anyway, not caring who saw.

He tasted like salt and ocean. Like home. He nuzzled his chin against her forehead.

“I’m glad everyone came,” she said.

It was quite a crowd. Down at the end of the beach, Maia, Simon, and Bat were playing volleyball with Anush. The vampires hadn’t shown up yet since the sun was still out, but Lily kept texting Alec to make sure they’d be providing O negative on ice for later. Isabelle was decorating the layer cake Aline had baked with icing frills, and Marisol and Beatriz were making a sandcastle. They both wore mourning white, and seemed to share a quiet, meditative sadness. Emma hoped they would be good for each other: both had lost someone they loved.

Jace and Clary had braved the water and were splashing each other as Ragnor drifted by on a massive pool float, drinking a lemonade. Jocelyn Fairchild and Luke Garroway sat with Jia, Patrick, and Maryse some distance down the beach, and Diana and Gwyn were cuddled together on a blanket near the shoreline.

“We have a lot of allies,” Julian said.

Emma’s gaze slid down the beach toward Magnus and Alec. “This is going to be an important night,” she said. “And it’s being shared with us. That’s not about having allies. That’s about having friends. We have a lot of friends.”

She figured he’d make a teasing retort; instead, his face softened.

“You’re right,” he said. “I guess we do.”

Keeping an eye on the kids had become habit. Even while playing at the tide line, digging up hermit crabs and letting them fuss up and down her hands, Dru kept a side-eye on Tavvy, Max, and Rafe. She knew they were all well looked after by a cadre of warlocks and anxious Shadowhunters, but she couldn’t help it.

“Drusilla?”

Jaime was coming down the beach toward her, just as he had when he’d come in response to Cristina’s summons. He looked healthier than he had then—less skinny, more color in his cheeks. Same wild black hair whipped by the wind, same sparkling brown eyes. He smiled down at her, and she wondered if she should have worn something more bright and pretty like the other girls. She’d been wearing black dresses everywhere for so long she barely thought about it, but maybe he’d think it was odd?

“So what’s in store for you after all this?” Jaime asked. “Are you going to go to the new Academy?”

The Downworlder-Shadowhunter Alliance had come together to build a new school for Shadowhunters in an already safe and warded location—Luke Garroway’s farm in upstate New York. According to reports, it was nearly done—and according to Simon, about a thousand times nicer than the old Academy, where he’d once found rats in his sock drawer.

“Not yet,” Dru said, and she saw the quick recall and realization in his eyes: She was too young to attend the new Academy, which began at fifteen. “Maybe in a few years.” She kicked at a seashell. “Will I see you again?”

He wore an expression she hadn’t seen on his face before. A sort of pained seriousness. “I don’t think that’s very likely. Cristina is leaving, so I’ve got no reason to come here any longer.” Dru’s heart sank. “I have to go back home to make things right with my father and the rest of my family. You know how it is. Family is the most important thing.”

She bit back the words she wanted to say.

“But maybe I’ll see you at the Academy someday,” he added. “Do you still have that knife I gave you?”

“Yes,” Dru said, a little worried. He’d said it was a gift—surely he wasn’t going to ask for it back?

“Good girl,” Jaime said. He ruffled her hair and walked away. She wanted to run after him and yank on his sleeve. Ask him to be her friend again. But not if he was going to treat her like a child, she reminded herself. She’d liked him because he acted as if she had a fully functioning brain. If he didn’t think so anymore . . .

“Dru!” It was Ty, barefoot and sandy, with a hermit crab he wanted to show her. It had a delicately spotted shell. She bent her head over his cupped hands, grateful for the distraction.

She let his voice flow around her as he turned the crab over in his careful, delicate hands. Things were different with her and Ty now. She was the only one besides Kit and Magnus who knew what had happened with his attempt to raise Livvy.

It was clear to her that Ty trusted her in a new way. That they kept each other’s secrets. She was the only one who knew that sometimes when he looked away and smiled he was smiling at Livvy’s ghost, and he was the only one who knew that she could pick a lock in under thirty seconds.

“There’s bioluminescence down at the other end of the beach,” Ty said, depositing the crab back onto the sand. It scurried for its hole. “Do you want to come see?”

She could still see Jaime, who had joined Maia and Diego and was chatting animatedly. She supposed she could go over to them and try to join the conversation, try to seem more grown-up and worth talking to. But I am thirteen, she thought. I’m thirteen and I’m worth talking to without pretending I’m something I’m not. And I’m not going to bother with anyone who doesn’t see that.

She picked up her long black skirt and raced after Ty down the beach, her footsteps scattering light.

“Okay, here,” Helen said, sitting down just at the tide line. She reached up to pull Aline down beside her. “We can watch the tide go out.”
