You do not shout. Shouting in the Spine is like kicking a choir of paper.

You kneel on the compass rose. You put two fingers on the inlaid N, the way Quill taught you last summer, and you say the greeting that is really a question: May I pass as a neighbor, not a blank?

A folio parts from a lower shelf. Quill is already there, of course. Ink-stained edges, small paper feet, a mouth that is a compass rose. Young for a living map, which still means older than your hill in patience.

“You saw the fade,” Quill says. Not a question. “If you chase a blank like a prize, the Spine comes apart.”

“Blank,” you repeat.

Quill points at the Atlas, then at Brask’s pencil, then at the empty air where last decade’s flood-mark is already too easy to forget. “A map is a choice. Pull the fen off the page, and the town forgets how to be a town with a sponge. Some books are like that. Some roads. Even a call number you cannot see from the square. The Atlas walks the last uncut seam of what is. Take the waste-label, and you take the seam.”

Tansy, at the edge of hearing, holds still like a good secret.

Quill’s rules are simple: no running at living pages, no ripping for fun, no taking what a place still needs.
