A gripping science thriller in the Arctic! Mysterious nanoparticles in a Greenland ice core confront biologist Nora Grimm with a fascinating puzzle. At first, she believes the 400,000-year-old ice is contaminated. But then the bizarre crystals suddenly show signs of life. Nora realizes that she has discovered far more than just prehistoric climate records. Also, Exobiologist Robert Greaves is on his way to Greenland to investigate a connection to a similar finding by the Mars rover Curiosity. Is this really an extraterrestrial life form that has been lying slumbering in obscurity since ancient times? What neither of them knows is that once before, the exploration of the ground of the Greenland glacier almost caused a catastrophe. In 1967, the secret U.S. nuclear base Camp Century was evacuated head over heels – to this day, nobody knows the true reasons. Now, the threat from that era has reawakened and seems eager to complete its mission – with fatal consequences for all life on Earth.
