Holly Black interviewed.

From Bildungsroman:

I'd love to visit Fantastica in The NeverEnding Story - referred to as Fantasia in the film adaptation - or Strangewood from Christopher Golden's book of the same title. If you could enter a mythological world other than those you've created, where would you go?

I think I would be tempted to visit a lot of places that would be ill-advised. I would be tempted to go to Michael Moorcock's Melbione, for example, despite the fact that I would probably be gutted within minutes of arriving and my tendons used to make some new kind of musical instrument. Or Tanith Lee's Don't Bite the Sun (lush setting! body swapping!), but her characters are often cold-blooded sociopaths so I worry that I would become lonely and paranoid. Rowling's world seems like it would be fun (think of the shopping!) until I realize that I'm a Muggle.

I guess I would most like to go to Charles de Lint's Newford, because I would get to have lots of artistic friends, the strong possibility of numinous mystical experiences, plenty of coffee, and a high expectation of being pretty safe. Also, because it's in Canada, I would have health insurance.

Seconded, re: Newford.  And don't miss her Top Ten Favorite Books list -- anyone who starts out their list with The Perilous Gard* obviously has super-duper taste.

*WHAT?  You haven't read it?  Git thee to a library!  Go on, git!
