China Mieville's first novel, "King Rat", is another story of an alternative London. Like "Neverwhere", or Mieville's own "Un Lun Dun", it concerns normal people dragged into a fantastic underworld of magic and myth. I'd say it is Mieville's best; a leaner, sleeker novel than his later New Crobuzon books. It scurries along at a hell of a pace, terrifying and exciting. Excellent stuff.
