Undr

From his dreams the most popular virtual realities are constructed - but he has disappeared into the abandoned tunnels beneath the beautiful city. And Alina Nemitz, a top executive with the Nets, will be thrown from her good life unless she finds him. But that forces her to return to her shadowy past. The only one who can help her is her ex-lover, Barkas Todd, whom she has ordered executed. And only Mikel Smith, a test-tube spy with no imagination, knows where the Dreamer is - if he doesn't fall victim to the Lady of the Awakening, leader of the Unreals.
Meanwhile, Symington, a bizarre recluse in the war-slagged wilderness outside the city, is preparing to invade it. Thus the Dreamer is scared. If he falls asleep, the Unreals - everything that has never existed and cannot even be imagined - will come crashing through his dreams and destroy reality.
