This doesn't feel like a cyberpunk novel, because most cyberpunk feel very much of their time, whereas this has a freshness to its exuberant vision that seems to disdain such strictures.

Rebel wakes up in Eucrasia's body. Rebel is an artificial persona that has come to life, though she is marked for death by the corporation that owns her. Literally of two minds, she escapes and goes on the run with Wyeth, a friend of Eucrasia's with an interesting mind-state of his own, and they jaunt across the cylinder cities and dyson spheres and ice comets of the solar system looking for answers and adventures and finding both.

It's a marvelous read, bright and energetic and crisp and fun, full of invention and strangeness. The cover for my edition is awful, but it isn't inaccurate and as such is just a single glimpse of the dizzying wonders of Swanwick's strange and alien future.
