The Infinity Shift

From the introduction: Welcome to the High Frequency Active Auroral Research Program! They call it HAARP. You call it the rear end of a two-year stint at the United States Air Force base in Gakona, Alaska. Nothing happens at HAARP - or at least nothing used to happen until they really turned on the machine for the first time. Now, everything happens there, all at once. Can you and your buddies survive one eternal shift at the center of all space-time?
