The space adventurers Pyrrus and Kerk decide to liberate their fellow colony members, who have seemingly been kidnapped to the dangerous ice planet Northworld. The underground societies on the planet consist of a labyrinth of interconnected cities and villages. The most violent criminals in the universe transported to this penalty colony have rebelled. Rescue will not be an easy task. Pyrrus and Kerk are facing their most difficult task to date. They encounter an icy climate with blood-icing enemies. Fighting the severe ice storms on the planet's surface is about to become the downfall of the space adventurers. The long walk becomes a frightening and endless nightmare.

The fifth novel about the space adventurers Pyrrus and Kerk, whose motto is ‘It will get better’.

‘When Kerk climbed over the next ice obstacle, he realized that something was wrong. His whole body suddenly trembled and a cold sweat broke out. His breathing was heavy and his legs refused to carry him. Everything around him disappeared in a haze of mist. His brain refused to function and his legs felt like jelly. He sank down on the ice.

The ice. 

The damn ice.’

‘Now, Pyrrus staggered in the icy wind. The storm seemed to get stronger. Kerk also felt the increasing strength in the wind. They now both walked on the hidden and unknown power reserves that a dead tired person is able to muster in extreme danger to life. But the reserves were not unlimited and their shaky steps showed that these reserves were also getting thin. And when they were finished, they would just fall into the shelter of some ice crater and wait for the deep, eternal sleep.’
