Afterwards (en Inglés) - L. J. Morten

Afterwards is a quiet, philosophical novel set aboard a British nuclear submarine after its missiles have already been launched. Cut off from all communications, the crew no longer knows whether their country still exists, only that duty has been carried out and silence remains. As hours pass with no word from the world above, routine begins to hollow out, authority is tested, and the meaning of obedience itself starts to fracture. This is not a story of apocalypse, but of aftermath: of men sealed beneath the Atlantic, forced to decide what duty means when there may be no nation left to serve.
