Eighteen years have passed since the Great Mission. The history of the famous campaign has managed to acquire legends; for the younger generation, it is more of a fairy tale than a true story. Peace and prosperity reign in the villages of the Chain. But in winter, instead of the usual rains, it began to snow. And every year summers are getting shorter, and winters are getting longer and colder.It seems that the planet is testing its children again. Again forcing them to take decisive steps. So, a new journey is ahead, this time - to the south. On the way, the heroes will again have to remember what war is. And who is the real enemy of humanity.*** The book is not a direct continuation of the Hostages of the Sun dilogy.It can be read as a separate work, but I still recommend starting with a dilogy - it will be so easier to understand the world and the characters. Hostages of the sun - the first book, Password Aurora - the second bookContains obscene language.
