A literal escape.
If you could, what utopian or dystopian world would you most want to live in, not just escape to in your reading?
Example: A good friend of mine wants to live in Austin Tappan Wright's "Islandia" (a utopia).
For me, I have one of each:
Utopia - "Lost Horizon" by James Hilton
Dystopia - Any of William Gibson's "Blue Ant" trilogy ("Pattern Recognition", "Spook Country", "Zero History")
What's yours?
