The way time travel is described is presented in Enemy Of The State is intriguing to me. Despite all the movies I’ve seen about it, I never thought about having to send yourself to the right SPACE as a part of time travel. Makes perfect sense though. With the earth traveling around the sun at 30 km/second, to travel back even 1 second to the spot you are sitting in now without accounting for where that spot is located in the invisible 3 dimensional grid of the universe, would be devastating. Once again FPW is the man, but my question is does anybody know any other awesome books about time travel. Older the better.
