From time to time
When Time and Again was published in 1970, it immediately developed a loyal following. Now, twenty-five years later, Jack Finney returns to the same magical territory and finds Ruben Prien still at work with the Project, still dreaming of altering man's fate by going back in time to adjust events...to interfere, some might say, with destiny.

Once again, his conduit to that bygone era, his messenger to that lost world, is Simon Morley, the man who actually proved himself capable of traveling back and forth in time. In From Time to Time, Rube's purpose in summoning Si back from that earlier world, where he has taken up permanent residence, is no less grand than an attempt to prevent World War I from erupting.
