Jenson Thorne had always been a vivid dreamer, but after an unusual encounter with a stranger who claims to have been in a dream with him, Jenson discovers that his dreams are not always a simple creation of his brain. In his search for answers, he meets a physicist named Dr. Donald Wesson, who truly puts the "mad" in "mad scientist." From Dr. Wesson, Jenson learns that a phenomenon exists called "dream jumping, " in which the consciousness of one body is able to transport itself into the body of parallel versions of oneself. When Jenson starts experimenting with dream jumping, he finds that there is one particular woman in many of these parallel worlds who captures his attention. He seeks to discover who she really is, what his connection is to her, and why he hasn't found her in his own world. Throughout his journey, he is forced to question all he knows about himself and struggles to find his place in the vastness of the universes.
