The Prisoners of Titan's Ruins

By 1958, rockets are new and empires watch the skies. An orbital penitentiary above Titan stores men labeled enemies of Earth — until ancient stone engines beneath Saturn awaken. Their rumble warps gravity, collapses cells and frees a chain of convicts and wardens into catacombs of cyclopean machinery. The 'electronic brain' of a captured probe becomes the ruins' interpreter; servomechanisms thought dead turn into custodial gods. Escape becomes a wager between stubborn humanity and a prehuman intelligence that remembers a different sun. A Cold‑War tale of rocket daring, moral compromise, and ruins that won't stay buried.
