As a young man David Jameson creates a time machine capable of allowing travel both into the future and into the past. However, thing about time travel is simple because cause doesn't necessarily precede effect! One day, before the time machine is even past the planning stage, David receives a visit from someone very special; his daughter Susan from the future! Susan is only eight years old and t yet born in David's present time frame but already she has experienced a lifetime's worth of grief having personally witnessed the horrifying effects of a new world war and the assassination of her father, David. She has made the jump from her own time back to the time before her father starts work on the time machine in order to persuade him t to build it! It seems that the World War II-era Nazis are hoping to use time travel to rewrite sixty years of world history following them winning the Second World War! Susan Jameson is successful in her mission but in rewriting history she has also written herself out of existence! In David's new timeline, he does t die at an early age from an assassin's bullet but he also never has a wife or a daughter named Susan and he finishes up a disgruntled and sick old man who never achieved anything worthwhile in his life. Somehow David must find a way to undo a life-altering mistake in order to make 'A Time for Susan' as well as prevent the World War II-Nazis from taking over the world!
