But all that unhappiness takes place far in the background. In the foreground, every summer for three years, the children leave their various boarding schools and return to Cornwall, and each time they do they find their way into the secret world of Fillory, where they have adventures and explore magical lands and defend the gentle creatures who live there against the various forces that menace them. The strangest and most persistent of those enemies is a veiled figure known only as the Watcherwoman, whose horological enchantments threaten to stall time itself, trapping all of Fillory at five o’clock on a particularly dreary, drizzly afternoon in late September.

Like most people Quentin read the Fillory books in grade school. Unlike most people—unlike James and Julia—he never got over them. They were where he went when he couldn’t deal with the real world, which was a lot. (The Fillory books were both a consolation for Julia not loving him and also probably a major reason why she didn’t.) And it was true, there was a strong whiff of the English nursery about them, and he felt secretly embarrassed when he got to the parts about the Cozy Horse, an enormous, affectionate equine creature who trots around Fillory by night on velvet hooves, and whose back is so broad you can sleep on it.

But there was a more seductive, more dangerous truth to Fillory that Quentin couldn’t let go of. It was almost like the Fillory books—especially the first one, The World in the Walls—were about reading itself. When the oldest Chatwin, melancholy Martin, opens the cabinet of the grandfather clock that stands in a dark, narrow back hallway in his aunt’s house and slips through into Fillory (Quentin always pictured him awkwardly pushing aside the pendulum, like the uvula of a monstrous throat), it’s like he’s opening the covers of a book, but a book that did what books always promised to do and never actually quite did: get you out, really out, of where you were and into somewhere better.

The world Martin discovers in the walls of his aunt’s house is a world of magical twilight, a landscape as black and white and stark as a printed page, with prickly stubblefields and rolling hills crisscrossed by old stone walls. In Fillory there’s an eclipse every day at noon, and seasons can last for a hundred years. Bare trees scratch at the sky. Pale green seas lap at narrow white beaches made of broken shells. In Fillory things mattered in a way they didn’t in this world. In Fillory you felt the appropriate emotions when things happened. Happiness was a real, actual, achievable possibility. It came when you called. Or no, it never left you in the first place.

They stood on the sidewalk in front of the house. The neighborhood was fancier here, with wide sidewalks and overhanging trees. The house was brick, the only unattached residential structure in a neighborhood of row houses and brownstones. It was locally famous for having played a role in the bloody, costly Battle of Brooklyn. It seemed to gently reproach the cars and streetlights around it with memories of its gracious Old Dutch past.
