Sand Storm

Fritz has stumbled upon a gateway that links distant points in space and time. He has already used it to help the United States end a dangerous standoff with another nation. Now the president is asking him to head off a nuclear threat in the Middle East.

For Fritz, visiting earlier eras is both exciting and educational, but protecting the planet is a far heavier responsibility. With the clock ticking, he must work out how the device operates while carrying out the president's requests.

As he goes, he has to wonder whether passing through the gateway could set off effects that reach well beyond what he currently grasps.
