About the book: 2022 / Three keepers of a radio beacon located slightly to the side of the busy space route disappeared without a trace. A full investigation has been carried out. Based on the results of the inspection, a banal violation of internal instructions was revealed. The lighthouse is turned on again, however, wanting to be on the safe side, management reinforces the team with a platoon of paramilitary guards. Navigation equipment is functioning properly again, ensuring traffic safety. It seemed that everything had returned to normal, but a battle is approaching and no one from such a small population of an asteroid stuffed with electronics has any idea who they will have to fight with and how long this battle will last.
