The book is a continuation of the books “Quantum Entanglement” and “Wanderer of Alien Worlds”. Warships of the Skhert civilization unexpectedly invade the space controlled by the civilization of earthlings and demand that Anton Kerasov be handed over to them. The earthlings refuse them this. The Skherts begin hostilities. Earthlings have no experience in space wars and they ask the Truck civilization for help. The trucks drive away the skerries. The Earthlings ask the Thrucks to share with them technologies to equip their warships with advanced weapons that would be able to adequately withstand the aggressive civilization of the Skherts, but the Thrucks offer the Earthlings to develop such technology themselves, only by providing the Earthlings with new materials for this. But earthlings must go for materials that are stored at one of the space truck bases themselves. The earthlings send their navigator Adam Stars after them. Having overcome a large number of obstacles, Adam Stars delivers materials to the civilization of earthlings.
