Chapter 1
The Keeper of Old Light
The vault under Segara Ridge held four hundred and eighty thousand nights, and Mara Zuhra knew the smell of every decade.
The 1920s smelled of shellac and camphor. The 1950s smelled faintly of vinegar, which was a chemical warning she checked with a wince, the way you check an elderly relative’s cough. The 1990s, the last years before the cameras went digital and the Southern Patrol ended, smelled of nothing at all, which always struck her as the saddest smell in the room.
Each envelope in the long wooden cabinets held one glass photographic plate, and each plate held one exposure of the southern sky, taken from this ridge on this island, which sat so nearly on the equator that the observatory’s founders had bragged the whole heavens passed over their dome: every constellation of the north, every constellation of the south, no star refused. For a hundred years, whatever else happened in the world, somebody on this mountain had opened the shutter and kept the night.
Mara was forty-two years old, and she was the last person on the staff list whose job it was to read them.
