I have too many friends who tell me that they spend the first hour of every morning going through their e-mail messages. I'd like to use my time more carefully.

In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.

All writers have roots they draw from - travel, work, family. My roots are in science and it is fertile ground for fiction.

Events, once happened, lose reality, alter with a glance, a storm, a night. In time, the past never happened. But who could know? Who could know that the past is not as solid as this instant.

"The Diagnosis" is by far my most ambitious book. I such great hopes for it... there was so much I wanted to do with the book. I was extremely insecure about it for several years. Just didn't know whether I would finish the book much less for it to come close to what I intended. I think that for any novel you never know exactly how the book is going to turn out...

In a world in which time is a circle, every handshake, every kiss, every birth, every word, will be repeated precisely.
