The Terminal Experiment has propelled Robert J. Sawyer into the limelight as one of science fiction's hot new writers, earning him the prestigious Nebula Award in the process. In this fast-paced thriller, Dr. Peter Hobson's investigations into death and afterlife lead him to create three separate electronic versions of himself: one has no memory of physical existence and represents life after death; one has no knowledge of death or aging and represents immortality; and the third is left unaltered as a control. But all three have escaped into the worldwide matrix...and one of them is a killer.
