Professor Bradley Williams' theory of the Extant Eternal had been a hotly-debated controversy in the scientific community and his published writings on the subject of space-time have been an embarrassment to the university at which he had been tenured. As an illustration in his classroom lectures, he had always suggested that the use of a specially-built time machine would prove out his theory if only such a machine could, in fact, be built. Secretly, he had worked for many years to build just such a machine. When the school's exasperated board of regents finally demands he surrender all of his research and any such machine that may exist, one of his students attempts to save her professor's work by using the machine to travel back in time to warn him of the impending actions by the board. But a miscalculation and errant settings on the machine send her back not just a few days, but back to 1865, the end of the Civil War, with no way to return. Instead of wallowing in self-pity (and after a couple of good cries), Elizabeth Spencer trepidously seizes upon the opportunity to definitively prove or disprove Williams' theory and with the help of a pair of unlikely allies, she sets off for Washington, D.C. to stop John Wilkes Booth's conspiracy and prevent the assassination of President Abraham Lincoln. Once again, author Bob Pierce leads readers on an adventure of vivid imagination, inviting them to follow a strong woman lead character who shows the indomitable human spirit of determination and the alarming realities that she discovers along the way. Hard revelations of self-discovery as she finds within herself the fortitude and strength to do what she needs to do to accomplish her mission, build relationships and defend the lives of those who rely on her as well as her own in a harsh and often life-threatening landscape of a battered people unwilling to completely admit defeat despite their leaders' surrender. With nothing to lose, she is resolved to sacrifice everything she has left, her very life, to protect the president and change the course of history.
