Twenty years after the mysterious disappearance of the Ishiguro, a new mission launches to investigate the anomaly where the original vessel vanished. Twin brothers Tomas and Mirakel Hyvönen lead the project, with Tomas managing operations from Earth while Mirakel serves aboard the new spacecraft. As the crew approaches the site of the original disappearance, they encounter physical and psychological phenomena that challenge their understanding of space and time. The narrative alternates between the perspectives of the brothers, creating a tension between the safety of the ground command and the isolation of deep space.

The novel is characterized by its focus on atmosphere and the psychological disintegration of its protagonists as they confront the unknown. The narrative structure highlights the disconnect between the mission control center and the crew, emphasizing the isolation inherent in deep-space travel. Readers often note the author's commitment to a somber, introspective tone that prioritizes character study over traditional space-faring tropes. The work functions as a meditation on the nature of loss and the human drive to seek answers in the void, suggesting a preference for philosophical inquiry over hard science fiction mechanics.
