She tested limits. A petty childhood promise vanished from her mind like a smudged note and the Top returned, lodged in the brass rim like a mote of light, the coordinates of a sinking beacon off the Saharan shelf. Those coordinates proved correct; the salvage paid in artifacts and coin, and in the tiny, accumulated victories that financed further curiosity. As the trades mounted, the Top’s appetite seemed to widen. It wanted not only memory but rhythm: habits, small loyalties, ways of seeing. Each exchange subtly rewired Norah. She could map wrecks with uncanny precision, anticipate storms by the edge of her intuition, but at the edges of night she sometimes misremembered faces—friends’ features blurred, names slipping like fish.
