Guardian - Paul  Alexander, Thomas F. Monteleone,  Paul Alexander Read about twenty-five years ago, now.

Not a particularly good novel (obviously since I didn't become a fan of Monteleone) about a post-nuclear holocaust world and the final battle between the two machines (one pro-human, the other anti-) that brought about the near-extinction of the human race (this was pre-Terminator.

What I really enjoyed about the novel was the prologue, which took the reader on a virtual tour of the civilizations that had grown up after the apocalypse.
