About the book: 2021 / Russian Empire, 1908. Very similar to the one that was, and yet different: here Emperor Alexander the Third is still on the throne, and children in schools read Pushkin’s poems, written during the siege of Sevastopol. But this empire is also on the verge of great upheavals... Popular unrest begins, underground fighters are making plans for an uprising, young people are dreaming of freedom. However, for boys enrolled in the Alexander Cadet Corps, this is not a reason to postpone their studies. For now, ordinary life continues: the cadets solve problems, analyze battle schemes, make friends and fight with each other. True, in six years the catastrophe will still break out. But can it be prevented? And, it would seem, what does the mysterious dungeons under the building have to do with it??..
