Ancillary Sword (Imperial Radch, #2)

by Ann Leckie

a box that Ship couldn’t see or sense. Human eyes could see it, even when those eyes were part of an ancillary body. But no scanner, no mechanical sensor could see that box, or the gun inside, or its ammunition—bullets that would burn through anything in the universe. How this had been managed was mysterious—not only the inexplicable bullets, but how light coming from the box or the gun might be visible to human eyes but not, say, to cameras, which in the end worked on the same principles. And Ship, for instance, didn’t see an empty space where the box was, where something ought to have been, but instead it saw whatever it might have expected would occupy that space. None of it made any sense. Still, it was the case.
