This audiobook is narrated by an AI Voice. Sealed inside a steel sphere no wider than a coffin, the explorer Elstead is lowered five miles down into the lightless deep – further than any living man has ever gone – to see what the ocean floor conceals. His colleagues on the surface expect crushing pressure, blind fish, perhaps nothing at all. What Elstead finds instead is a glimmering city in the abyss, and a race of intelligent, reptilian beings who gaze up at his descending light and take the strange visitor from above for something other than a man. He returns with a tale almost too wondrous to credit – and a fixed resolve to go down again. But the deep does not always give back what it borrows.
