Vurt

But no review can do Noon's writing justice: it's a phantasmagoric combination of the more imaginative science fiction masters, such as Phillip K. Dick, genres such as cyberpunk and pulp fiction, and drug culture.

If this tickles your fancy, you should definitely consider the sequel to Vurt, Pollen, or Noon's lighter and more accessible Automated Alice, a modern recasting of Lewis Carroll's Alice in Wonderland.
