It was an amazing outpouring of collective joy. Quentin had forgotten he was capable of that emotion, the way a lost spelunker feels like there never was such a thing as sunlight, that it was just a cruel fiction. They chased one another around in circles, panting and rolling and acting like idiots. It was funny, Quentin thought, with his stupid little miniature fox brain, the way he could automatically recognize everybody as foxes. That was Eliot with the snaggle-teeth. That plump blue-white critter was Josh. That small, silky specimen with the wide eyes was Alice.

Somewhere in the goofing off a game spontaneously evolved. It had something to do with pushing around a chunk of ice with your paws and your nose as fast as possible. Beyond that the point of the game wasn’t really clear, but they frantically pounced on the chunk of ice, or pounced on whoever had pounced on it just before them, and pushed it until the next person pounced on them.

An Arctic fox’s eyes weren’t all that much to brag about, but its nose was unbelievable. Quentin’s new nose was a Goddamned sensory masterpiece. Even in the middle of the fray he could recognize classmates by snuffing their fur. Increasingly, Quentin noticed one scent more than the others. It was a sharp, acrid, skunky musk that probably would have smelled like cat piss to a human being, but to a fox it was like a drug. He caught flashes of it in the fray every few minutes, and every time he did it grabbed his attention and jerked him around like a fish on a hook.

Something was happening to the game. It was losing its cohesion. Quentin was still playing, but fewer and fewer of his fellow foxes were playing with him. Eliot lit out in a streak off into the snow dunes. The pack dwindled to ten, then eight. Where were they going? Quentin’s fox brain barked. And what the hell was that unbe-fucking-lievable smell he kept stumbling on? There it was again! This time he tackled the source of the smell, buried his snuffling muzzle in her fur, because of course he had known all along, with what was left of his consciousness, that what he was smelling was Alice.

It was totally against the rules, but breaking the rules turned out to be as much fun as obeying them. How had he never figured that out before? The others were playing more and more wildly—they weren’t even trying to go after the chunk of ice anymore—and the game was disintegrating into little knots of tussling foxes, and he was tussling with Alice. Vulpine hormones and instincts were powering up, taking over, manhandling what was left of his rational human mind.
