A reader who’s met Ruso via audio books got in touch the other day with a good point – if you don’t have a printed copy, you can’t see the map. This is no problem with the first book since it doesn’t have a map anyway – find Chester in north-west England and that’s Deva. In fact if you zoom in on the street plan of the modern city centre, you can still see the layout of the main streets in the Roman fort (they cross where Watergate Street now meets the top of Bridge Street).
Ruso and the Demented Doctor/Terra Incognita DOES have a map. I don’t have a final version to post on the site and don’t know whether I’d be able to anyway (copyright, etc). However…for anyone who’s wondering where the locations are, the Book II page now has a picture of what the longsuffering publishers received and had to untangle in order to produce the proper map. I hope it makes some sort of sense, and thanks to Laurie for pointing this out.
