The Terminator

In 2029, machines rule a devastated Earth, and the human resistance sends soldier Kyle Reese back to 1984 Los Angeles with one mission: find and protect Sarah Connor before the T-800, a nearly unstoppable cyborg killer sent by the same enemy, can eliminate her. Neither Reese nor Sarah yet know why one ordinary waitress matters enough to kill, only that the machine will not stop until she's dead. The authorized novelization of James Cameron's film.
