The handsome young Torvald has decided to marry Svyatoslav, but she is still a schoolgirl and not ready to get married. But that's not the half of it. Torvald is a Scandinavian warrior. He is one of those who travelled the lands of Ukraine more than a thousand years ago... And it all started with a discovery - a thunder amulet.
The god Thor said that this discovery is unusual: the amulet chose Svyatoslav, and now not only the present, but also the past depends on her.
Aware of the need to save the world, Svyatoslav and her friend Sasha go on the most dangerous journey through time in their lives.They have to overcome numerous trials: an old sorcerer sends them for a treasure that gives power over people; they miraculously escape from an aggressive dead man and experience many other dangerous adventures.
And the biggest surprise for them is the realisation that strength and power come not from magic, jewels, or powerful weapons...
