The SatNav of Doom, the fifth in the Banned Underground fantasy collection is now released. This is a stand-alone work; previous experience and licensing are not required.

Something always seems to happen when the Banned Underground, a dwarf rhythm-and-blues band led by a jazz-loving bog troll, are playing. Sadly for them, it is rarely anything good - for them at least. The rest of us always seem to get a good laugh at their predicament. But their world contains more than just pubs and pizza places. There is a Dark Side to some of the people they know: and to one in particular, of course: the Dark Lord of Keswick.

Once again, the Dark Lord has a cunning plan. And once again someone else is going to have to carry it out for him: that's what henchmen are for, isn't it? To hench? Oh, and to be sent on the risky missions ...

Not that this mission should be risky. What could be easier than secretly inserting computer spyware into a laptop, using a Banned Underground gig as a diversion? The Tax Office probably does it all the time. But the Tax Office is not normally being chased for an unpaid credit card bill for a huge round of drinks. (That's our politicians. And the Dark Lord's henchmen, of course.)

And it isn't just any laptop the Dark Lord wants to spy on either. The Government is struggling to find the way out of the Recession without a road map, and what better aid than a SatNav linked to an economic forecasting computer? If the Dark Lord can get inside information on future economic policy, maybe he can clean up and buy a new Mercedes at last.

Then there is a mystery: where did the time-travelling SatNav come from in the first place? What if the original owner wants it back?

Magic, mayhem and macro-economic policy collide in the latest surreal installment of the acclaimed comic fantasy collection, The Banned Underground.
