In this combination of the novels New Frontier and Final Frontier, this is the story of alternate timelines, partial political thriller, and time travel, in which a United States President is kept from being assassinated, but there are other unintended consequences as a result.

In 1976, Ronald Reagan becomes President of the United States, declares the U.S. will plant a base on the moon by 1980 and a base on Mars by 1989. The Iranian Hostage Crisis occurs, but Reagan issues a stronger response, but as a result, Osama bin Laden rises to power earlier than he normally would have in the prime timeline. Meanwhile, The Soviet Union decides to build a starship that will travel to the stars because they want to one-up the United States, but as is usually the case, nothing seems to go right.

In the early 1990s the U.S. and the Russians join forces, which leads the joint venture to the other side of the galaxy by means of a wormhole. When they attempt to return to Earth, they find themselves in the past, where they try to fix certain events in the past while they wait for history in general to catch up to where they launched the joint mission to begin with. Things go wrong as events do not play out as planned and numerous cases of unintended consequences result from the multiple attempts at fixing the timeline.
