In 2057, Saturn's moon Janus suddenly went out of orbit and rushed outside the solar system. Until now, no one suspected that this giant block is an artificial formation, the brainchild of alien technologies. Only a ship of comet hunters, space ice miners, is able to keep up with it. Captain Bella Lind is invited to follow the runaway moon, because for humanity this is a long-awaited chance to establish contact with extraterrestrial intelligence. Bella could not have predicted that the men who had given her this mission would not hesitate to leave her crew in the lurch. For the first time in Russian!
