Goodreads asked Dennis E. Taylor:

If you could travel to any fictional book world, where would you go and what would you do there?

Dennis E. Taylor That's a hard one. Some of the most interesting worlds are ones that you wouldn't necessarily want to be a part of. What's that old saying, "An adventure is something that happens to someone else, far away". Something like that.
As a general statement, I'd want to be part of a world where they've invented one or more of immortality, FTL, or time travel. As long as it's not too dystopian otherwise.
