Druso, or the Stolen World of Humankind (1931) is a classic alien invasion tale.
German protagonist-narrator Alf Bentink and his pregnant Swedish wife Judith Thyrberg undergo the suspended animation process called 'Somnium' (a nod to Johannes Kepler?) expecting to be revived within a hundred years, they are actually awakened three centuries later to find Planet Earth under the dominion of the wandering Planet Druso; the 'robber star'.
The insectoid Drusonians rule most of the now 'barabarized' human race via Oracles and 'return to nature!' priests, except for the 'Atlanteans' who hide at Boothia Felix at the North Pole, where the invaders cannot tolerate the cold, plotting to break the electromagnetic chain binding the parasite planetoid to Earth...
At the climax Bentink must rescue Judith, and their infant daughter Urania, when they are taken to Druso; where selected humans are brought for petting, service, milk and meat...
