"Humanity has known the true nature of consciousness."

Europa, the second moon of Jupiter. Beneath its surface of thick, absolute-zero ice lies a vast liquid ocean, exceeding the volume of all Earth's seas combined.

What human explorers witnessed in that abyss was unimaginable. In the dark depths beneath the ice, a colossal structure of glowing neural circuits and quantum networks stretched across the entire globe. It revealed a shocking truth: the celestial body of Europa itself is one massive "thinking brain."

Dwarfed by intelligence on such an overwhelming scale, humanity is insignificant. Yet, in this icy ocean, they are forced to confront fundamental answers to questions they have long pursued: "What is consciousness?" and "What is a story?"

This is not merely an encounter with the unknown. It is a thrilling, awe-inspiring philosophical hard SF epic that explores the depths of consciousness through the lens of quantum mechanics.
