Goodreads asked Mabh Savage:

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

Mabh Savage (Minor spoilers for The Long Earth)
That’s really difficult as most are quite dangerous in some way, and while I have a romantic urge towards adventure, getting eaten by a dragon or blown up isn't necessarily tempting! Maybe the science fiction realm of the Long Earth (Baxter, Pratchett) as the idea of sliding in between parallel and mostly unspoilt versions of Earth is beautiful.
