Five people in search of truth and comfort. Katharina Hagen's novel takes us to the Northern Lights in the breathtaking expanse of Canada. It tells the story of individuals who have lost something - love, a friend, a mother, or themselves. There is botanist Daphne Holt, who searches for a friend in the Canadian wilderness and stumbles upon a secret. There is the musician in his houseboat, fulfilling his late wife's last wish while waiting for the Northern Lights on the frozen lake. Twelve-year-old Richard sees possible paths to the planet Tschu, where he believes his mother and sister are. And there is the confused lady, in whose mind the white emptiness has already spread completely. Finally, the narrator invents her own story, a thriller about the crimes of a ruthless oil company, in which she herself finds her life in danger.
