Guards! Guards!

Insurrection is in the air in the city of Ankh-Morpork. The Haves and Have-Nots are about to face off. Again.

It’s old news to Captain Sam Vimes of the city’s ramshackle Night Watch. But this time, something is different—the Have-Nots have found the key to a dormant, lethal weapon that even they can’t fully control, and they’re about to unleash a campaign of terror on the city.

Long believed extinct, a draco nobilis can now be seen patrolling the skies above Discworld's greatest city. Not only does this unwelcome visitor have a nasty habit of charbroiling everything in its path, but it’s also soon crowned King.

Can Vimes, Captain Carrot, and the rest of the Ankh-Morpork City Watch restore order (before it's burned to a crisp)?
