« Guards! Guards! » Terry Pratchett

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 …).

Meanwhile, back at Unseen University, an ancient and long–forgotten volume — The Summoning of Dragons — is missing from the Library’s shelves. To the rescue come Captain Vimes, Constable Carrot, and the rest of the Night Watch who, along with other brave citizens, risk everything, including a good roasting, to dethrone the flying monarch and restore order to Ankh–Morpork (before it’s burned to a crisp).
