"Something is happening to Green. He is an ordinary guy, time-jumping forward at a startling, uncontainable rate. He is grappling to understand his present; his relationship is wholly tattered; his ultimate destination is a colossal question mark. Zada is a scientist in the future. She is mindful of Green's conundrum and seeks to unravel it by going backwards in time. Can she stop him from jumping to infinity?"--Provided by publisher.
