Query: Gibson's back!

After giving the world of science fiction a swift kick in the pants with "Neuromancer," Gibson's novels dropped in quality like a brick into a black hole.But then "Idoru" comes along, redeeming the venerable creator of the cyberpunk subgenre. The characterization is "just enough," the imagery is stunning, and the story is quickly accessible and not at all frustrating as prior novels had been. And it's a clever story, too, with unique ideas.I don't want to give them away, but pick it up. If you remained loyal to Gibson, you'll see some familiar faces along the way, too. And if you've never read a cyberpunk novel before, go ahead and start with "Idoru" ... "Neuromancer" will always be waiting.
