Five years after the Challenger disaster, NASA launched their newest space shuttle, Endeavor, in a dramatic return to space. But several moments after lift-off, Endeavor exploded over the ocean, taking the lives of all its crew members, and killing the United States' space program.

It's 2009, seventeen years after the Endeavor tragedy in 1992, and NASA has been made part of the Department of Defense. America's civilian space program has been permanently discontinued for over fifteen years.

Daniel Marks, the Chief Programmer at a research facility in New Mexico, is working on a cutting-edge electromagnetic device. While developing the controller software for the device, an accident occurs and he suddenly finds himself back in his old life in 1992.

With his unique knowledge of the future, what should he do with his new life? Should he use his knowledge simply for personal gain, or should he risk his freedom and future to stop a national disaster before it happens?
