The first three books in Michael R. Stern's 'Quantum Touch', a series of time travel science fiction novels, now in one volume!

Storm Portal: When history teacher Fritz Russell walks through his classroom door, he doesn't expect to meet General Robert E. Lee on the day after the surrender at Appomattox. A lover of history, Fritz finds his sudden time trip to the past both a gift and a chance for great adventure. But when a portal opens to the Oval Office, he realizes that this mysterious gate could also be put to serious purpose. Fritz does not believe there is any danger in traveling across time and space, but will his own government consider him expendable if he cannot solve the mystery of the portal?

Sand Storm: After Fritz Russell discovered a portal through space and time, he helped the United States resolve a foreign crisis. Now, the president wants him to use the portal to avert a nuclear threat in the Middle East. For a history teacher, traveling to the past is entertaining and enlightening, but Fritz can't be sure if using the portal has other, long-reaching consequences. No matter what he chooses, one question remains: does he have enough time to learn the mysteries of the portal?

Shadow Storm: An ominous shadow has been cast by a hidden enemy, who's planning to drive the world into turmoil. As Fritz himself becomes a target, the portal seems to be the only way he can end the growing danger and bring peace to the globe. But the voice in the shadows believes they cannot thwart his plan, and will do everything in his power to bring chaos to the world.
