1979, 1984, Tempo, New York
Luke goes to work for a physics professor in London who is conducting an experiment to create a window into the past.
I was expecting this to be a fantasy story due to the cover, but it was a nifty little sci-fi. The premise was interesting, though very predictable and I thought that the characters were three-dimensional and their motivations were well described.
