Terminator 2: The New John Connor Chronicles: An Evil Hour is the Second novel in a series of three novels, written by Russell Blackford.
Though the main characters within the books are based upon the films mythology Terminator 2: Judgment Day, they appear to have no connection with the Terminator: The Sarah Connor Chronicles TV series or Terminator 3: Rise of the Machines. The novel criss-cross's between two realities, one that follows on from the film, and another more sinister one known as "Skynet's world" which gives an alternate plot from approximately half way through the film's timeline.
Judgment Day is coming! Following the events of Book 1 (Dark Futures), the future war between the human Resistance and the forces of Skynet takes an unusual twist as Terminators from an alternate timeline invade the world of John Connor and his mother, Sarah, seeking to bring about the inevitable war that the Connors had merely delayed with their actions. But another cyborg has travelled across the dimensions to protect John—and nothing is going to prevent her from carrying out her mission!
