Intelligence has discovered a secret Soviet space station spying on America, and Apollo 18 may be the only chance to stop it. But even as Kaz races to keep the NASA crew one step ahead of their Russian rivals, a deadly accident reveals that not everyone involved is quite who they were thought to be. With political stakes stretched to the breaking point, the White House and the Kremlin can only watch as their astronauts collide on the lunar surface, far beyond the reach of law or rescue" -- Front jacket flap.
