I got a mention on the Terry Pratchett message boards!
Soon the world will be able to enjoy what I and the editors at Wizard Boooks have already seen for months now, and that's Stephen's fantastic illustrations for Stormslayer. I'll see if I can post some here soon, but for the time being you'll have to settle for his painting of the Ice Elemental from the front cover.
In other Pratchett-related news, the next Discworld novel Unseen Academicals is out in hardback in October with another brilliant cover by Paul Kidby. And if you're over in Arizona in September, you could take part in the First North American Discworld Convention a.k.a. The Turtle Moves! guest staring TP himself.
