From one of the most original voices in imaginative fiction comes a stunning novel of suspense and speculation, as a scientist seeking to uncover the mystery of human consciousness finds himself in a desperate search for immortality.

Dr. Jonathan Briggs is a gifted neuroscientist researching the existence of the human soul. Working at one of the world's top facilities, he has access to the latest technology. He also has the enthusiastic support of his lover, Alynn Reed, who made her fortune as a creator of virtual reality games that have broken every barrier. Alynn believes in reincarnation, which Jonathan scoffs at--until he begins to note strange anomalies in his research.

Then Jonathan's life is suddenly, shockingly turned upside down. No longer the dispassionate scientist, he begins a fevered, reckless effort to go beyond belief to proof. Ridiculed by his colleagues and the tabloid media, hounded by the police, Jonathan finds himself in a frenzied race against time, memory, and his own mortality. As he journeys deeper into the labyrinth of the human psyche, he moves nearer the place where past and future intersect, identities mingle, and death is the beginning of the most amazing adventure of all.
