Plum didn’t think her friends would have made fun of Quentin at that moment. For a while she’d fallen into the habit of thinking of him as a peer, basically, but over the past week she’d been reminded that he was a decade older and doing magic on a different level from her. Right now he looked like a young Prospero in his prime. He’d taken off his jacket and rolled up the sleeves of his white dress shirt, which was wringing with sweat. He must have been tired but his voice was still firm and resonant, and his fingers were working with a practiced crispness through positions she’d never seen before, the tendons standing out on the backs of his hands. This was the kind of magic, Plum thought, she would do when she grew up.

Big surges of power were flowing through the room. It crossed her mind that spells like this were exactly what turned people into niffins, when they got out of hand. Huge tranches and structures of magic that so far she’d only ever seen in isolation were colliding and interacting like weather systems. The intensity doubled and redoubled itself. Without warning the room juddered and dropped, leaving them in free fall for an instant—if it had been an airplane the oxygen masks would have come down. Quentin’s voice sounded artificially deep, and he’d started to tremble with the effort of keeping everything together. He hastily dragged an arm across his forehead.

“Staff,” he said. “Staff!”

The second time he barked it, loudly, and Plum snapped awake and turned and grabbed the black wood staff from where it stood leaned up in one corner.

He was hitting the panic button. Quentin grabbed the staff from her quickly, blindly, and as soon as it was in his hands it began jerking and vibrating, like it was attached to a line with an enormous fish on the other end, or a giant kite caught in a high wind.

She moved to help him, but he shook his head.

“Better not touch me,” he said through clenched teeth. “Could be bad.”

The air was thick with the smell of burning metal and the sweat of tired magicians. She could sense it in the room with them now, the land itself: an angry, hungry, thirsty infant thing demanding life, ready to take it from them if it had to. It cried out with an almost human voice. A spray of golden light erupted from between one of Quentin’s fingers: that must have been one of Mayakovsky’s coins going. Scenery raced past the windows, all of them now, too blurred to make out.

Space distorted grotesquely, and for an instant the room looked stretched out of all proportion, fish-eyed, as if a bulbous blister had formed on the surface of reality itself. Plum was scared of what would happen if it burst.
