The first mission to Europa - Jupiter's enigmatic moon - has landed, and humanity's darkest fears are about to awaken. For years, mankind has speculated that this frozen world harbours a hidden ocean twice the size of all Earth's oceans combined - an ocean potentially teeming with life. Driven by this tantalising mystery, they venture forth to unlock its secrets. But what they discover in the abyssal depths is far beyond anything they could have imagined. Nearly 400 million miles from Earth, their search for life has succeeded. But in their triumph, they overlook the most terrifying truth: what they have found is something far older and more horrifying than they ever could have conceived. Something has been trapped in the dark for eons - watching, and waiting, for them. Now, the crew stands at the threshold of unimaginable terror, realising too late that Hell, in its purest form, is cold.
