On a warm summer day in 1900, John Hendrix—the village idiot of Oak Ridge, Tennessee—lay in the woods and heard the voice of God. He emerged from the forest 40 days later with an impossible prophecy: this isolated valley would someday be filled with great buildings and factories that would help win the greatest war ever fought. Decades later, in 1942, everything he predicted came true.

The Manhattan Project chose Oak Ridge as its headquarters, transforming 3,000 rural farmers into 75,000 government workers literally overnight. For seven years, Oak Ridge existed as America's fifth-largest city—but it didn't appear on any map, every road was gated by armed guards, and most residents had no idea they were building the atomic bomb. This is the story of how small-town Tennessee politics, Albert Einstein's warning letter, and one madman's prophecy created the secret city that changed human history forever.
