The air smelled of brine. Inside the wave, he could see things moving. Eels and sharks snapping their jaws. Salt spray splashed Call’s face as the whole thing crashed down … and disappeared.

Everyone burst into applause. Call would have clapped, too, if he hadn’t been holding Havoc’s leash in one hand. Havoc was whining and nosing his fur. He hated being wet.

“Water,” Tamara finished with a laugh. “Once, when it was really hot, he came over and made a massive sprinkler right next to the pool. We all ran through it, even Kimiya.”

“What do you mean, even Kimiya?” came a teasing voice. “I like water as much as anyone else!” Tamara’s older sister, wearing a silver dress and sandals, had come up behind them. Holding her hand was Alex Strike, who was heading into his fourth year at the Magisterium and was Master Rufus’s frequent assistant. He was dressed down in jeans and a T-shirt, with a bronze band at his wrist, since he hadn’t gotten his silver one yet. He grinned at Call.

“Hey, squirt,” he said.

Call smiled a little awkwardly. Alex had always been nice to him, but he hadn’t known Alex was dating Tamara’s older sister. Kimiya was really pretty and popular, and Call always felt as if he were about to fall over or set himself on fire when he was around her. It made sense that two popular people were together, but it also made him more conscious of a lot of other things — his limp, his messy hair, the fact he was standing there in Aaron’s borrowed clothes.

Master Cameron finished his display with a flourish — sparkling droplets that shot out toward the guests. Everyone squealed, anticipating getting wet, but the water evaporated a few feet above the heads of the crowd, turning into wisps of colored vapor. Mr. and Mrs. Rajavi led the applause as another mage stepped forward, this one a tall woman with a magnificent crown of silver hair. Call recognized her as the woman who had brushed past him imperiously on the front steps.

“Anastasia Tarquin,” said Tamara in a whisper. “She’s Alex’s stepmother.”

“That she is,” Alex confirmed. His expression as he watched her was neutral. Call wondered if he liked her. When Call had been younger, he’d wished his dad would get married again so he could have a stepmother; it seemed better than no mother at all. Only when he was older had he stopped to wonder what would have happened if his dad had married someone he didn’t like.

Anastasia Tarquin raised both hands imperiously, holding thin metal rods in each. When she let them go, they lined themselves up in the air in front of her. She twitched her fingers, and one of them vibrated, sending out a single perfect note of music. Call jumped in surprise.

Alex looked over at him. “Cool, huh? When you master metal, you’ll be able to get it to vibrate to whatever frequency you want.”

The other metal rods were trembling now, each one of them like a different guitar string being plucked, sending out a torrent of music. Call liked music as much as the next person, but he’d never really thought about it before, about how alchemical magic could be used not just to build up and defend, or to attack and battle, but to make art. The music was like rain breaking through the humid air; it made him think of waterfalls and snow and ice floes far out in the ocean.

When the last note of the music died away, the metal rods dropped, falling to the earth and melting into it like rainwater sinking into mud. Mrs. Tarquin bowed and stepped back amid a shower of applause. As she moved away, she winked in Alex’s direction. Maybe they got along after all.

“And now,” said Mr. Rajavi, “perhaps our very own Makar, Aaron Stewart, would favor us with a demonstration of chaos magic?”
