With no conscious thought or apparent effort, he and his classmates fell into the classic ragged V formation, with a Fourth Year named Georgia at the apex. Georgia was the daughter of the receptionist at a car dealership in Michigan, and she had come here against her family’s will—unlike Quentin, she had confessed fully the nature of Brakebills, and as a reward for her honesty Georgia’s parents had tried to have her committed. Thanks to Fogg’s subtle spellcraft Georgia’s parents believed her to be attending a vocational institute for troubled adults. Now Georgia, whose Discipline was an obscure branch of Healing roughly analogous to endocrinology, and who wore her wiry black hair cinched at the back with a tortoiseshell barrette, was leading them southward, her brand-new wings pumping vigorously.

It was just chance; any one of them could have led the flock. Quentin was vaguely aware that, although he’d lost the lion’s share of his cognitive capacity in the transformation, he’d also picked up a couple of new senses. One had to do with air: he could perceive wind speed and direction and air temperature as clearly as whorls of smoke in a wind tunnel. The sky now appeared to him as a three-dimensional map of currents and eddies, friendly rising heat plumes and dense dangerous sinks of cool air. He could feel the prickle of distant cumulus clouds swapping bursts of positive and negative electrical charge. Quentin’s sense of direction had sharpened, too, to the point where it felt like he had a finely engineered compass floating in oil, perfectly balanced, at the center of his brain.

He could feel invisible tracks and rails extending away from him through the air in all directions into the blue distance. They were the Earth’s lines of magnetic force, and it was along one of these rails that Georgia was leading them. She was taking them south. By dawn they were a mile up and doing sixty miles an hour, overtaking cars on the Hudson Parkway below them.

They passed New York City, a stony encrustation crackling with alien heat and electrical sparks and exuding toxic flatulence. They flew all day, following the coastline, past Trenton and Philadelphia, sometimes over sea, sometimes over frozen fields, surfing the temperature gradients, boosted by updrafts, transferring seamlessly from current to current as one petered out and the next one kicked in. It felt fantastic. Quentin couldn’t imagine stopping. He couldn’t believe how strong he was, how many wing beats he had stored up in his iron chest muscles. He just couldn’t contain himself. He had to talk about it.

“Honk!” he yelled. “Honk honk honk honk honk honk honk!”

His classmates agreed.
