I have waited my whole life

Deckles stands, straightens his robe, braces himself, and gives the shelves behind the desk a sharp shove. They swivel smoothly and silently — it's as if they're weightless, drifting in space — and as they draw apart, they reveal a shadowed space beyond, where wide steps curl down into darkness. Deckles stretches an arm to invite us forward. "Festina lente," he says matter-of-factly.

Neel takes a sharp breath and I know exactly what it means. It means: I have waited my whole life to walk through a secret passage built into a bookshelf.
