It is a world turned upside down a world created when a future time traveler re-directs the course of World War II. The United States has suffered six decades of oppressive fascist rule. Now, while a decimated band of expatriate American rebels fight to liberate their country, international dissension threatens a nuclear holocaust. Tony Shane-a rebel with a dangerous, incredible plan-has inherited wartime secrets that might free his country: a plan derived from Albert Einstein-whose cryptic legacy conceals an improbable time travel strategy. To unravel the secrets of "Einstein's tunnel," Shane persuades Sarah Stenstrom-a beautiful young scientist in a Nazi cyber-research laboratory-to join his cause. But their intimate relationship soon threatens the entire mission. Vito Mironi-a powerful mob boss within a corrupt Nazi regime-secretly supports the rebels. But the reality of Einstein's plan soon converts Mironi into Shane's most dangerous adversary. Joining Shane's desperate odyssey is a ruthless rebel assassin, Salom, with a burning personal agenda. But only Nathan Carothers-charismatic rebel leader-knows the true dark purpose underlying their mission. Confronted by surprising obstacles, Tony Shane traverses a perilous path-while racing a deadly doomsday clock-to fulfill the promise of Einstein's Tunnel.
