About this book

Here there be dragons ... and the denizens of Ankh-Morpork wish one huge firebreather would return from whence it came. Long believed extinct, a superb specimen of draco nobilis ("noble dragon" for those who don't understand italics) has appeared in Discworld's greatest city.

Not only does this unwelcome visitor have a nasty habit of charbroiling everything in its path, in rather short order it is crowned King (it is a noble dragon, after all ... ).
