We've had it established that there are many multiple dimensions, and it takes a particular power to move from one to the other – the power to Walk. Joey Harker, who it seems could get lost between his garden gate and the front door, is one of the more powerful and talented Walkers, and has been employed by an agency that has to keep the balance in the multiverses, forever fighting between the powers of science and those of magic. But two years on from [[Interworld by Neil Gaiman and Michael Reaves|the original book]] we find that the agency is still a very uneasy place to be – picking up further Walkers, but opening itself up to strange events, unusual characters and unaccountable problems.
