1. Alternate History Premise In 1962, diplomacy fails and the Cuban Missile Crisis erupts into a full-scale nuclear exchange between the U.S. and the Soviet Union. Major cities across both hemispheres are obliterated. By the 1990s, civilization clings to survival in isolated, militarized zones, ruled by remnants of governments and warlords scavenging from the ashes. 2. Main Character Concept A former Soviet linguist turned codebreaker, now living in the irradiated ruins of what was once Berlin, is haunted by intercepted transmissions she failed to decrypt in time. She is recruited by a rogue peace-seeking faction trying to rebuild a global alliance through old Cold War secrets. 3. Central Conflict or Challenge She must decode a final encrypted Soviet contingency plan that could unite scattered survivors—or trigger another catastrophe. But rival factions will do anything to control it, and her past loyalty to a now-vanished regime makes her a target from all sides. 4.
