Ajda, Plamen, Mila, and little Samo head north from Thessaloniki, where they spent the winter, and where Vuk, Vlad, and Asurian are still trying to pull Ahmetaj out of the cave. In front of Ognjen stands a huge army of Lasoto's son Vladimir, who wants to take command of all the Slavs. Will the brothers fight each other? All, however, takes place in the shadow of a looming great battle that is inevitably approaching. Emperor Mavricij is determined to destroy the Slavs and the Avars, or at least expel them from his territory. How will Veles, the god of war, decide? Will all our heroes also endure until the fifth, last part of the series?
Youth fiction is set in the time and place of the migration of nations at the end of the 6th century. The author places five Slavic army commander’s children at the center of the events, who, while their father expands the Slavic territory to the west, are left to the mercy of his opponents, who see children as a means of extortion. But Ognjen's children are far from an easy opponent: the cunning healer Ajda, the beautiful Mila, who is followed by all the animals, and the triplets - masters of the sling, the bow, and the sword – are determined to not give up that easily. In the tense novel, the author captures the turbulent events of this historical period and interweaves them with his imagination. Throughout the story, important historical figures and events come forth. For example, what fate befell the Byzantine emperor Mavricij, who also appears in the fourth part? Does his life story, which follows historical facts, end there?
