About the book: year / Biker Svyatoslav Rusov, caught on the way by bad weather, decided to leave the highway and wait out the thunderstorm in the nearest forest. A lightning strike, a flash in the eyes and... Rusov's consciousness is transported many centuries ago and merges with the consciousness of sixteen-year-old Prince Svyatoslav Igorevich from the Rurik family, the son of the famous Princess Olga. 10th century Slavic tribes are on the verge of forming a single state. But they are not destined to cross this threshold - instead of uniting against common external enemies, the tribes will begin to quarrel and quarrel over petty grievances, incited by agents of the Khazar Kaganate and the Byzantine Empire. Will the young prince be able to create a powerful state and repel his arrogant neighbors?
