About the book: 2022 / Jan Barella works in a test sample of the Hut-1 bunker, which he himself designed. Knowing every detail of the structure, he is surprised by the frequent breakdowns, but conscientiously repairs them together with his colleagues. At the end of his watch, the electricity stops flowing, critical systems fail, and there is nowhere to wait for help. The only way to survive and save the rest of the shelter workers is to restore power supply.
