But crime stops for nothing, as Commander Sam Vimes of the City Watch knows. When a notorious serial killer emerges from hiding, the chase leads the Watch to the roofs of Unseen University where a magical storm is brewing. It's a case of wrong place, very wrong time. For Vimes finds himself back in his own rough, tough past with only a killer for company and a city on the brink of revolution to contend with. But he must survive, because he has a job to do: track down the murderer and change the outcome of the rebellion. And get back to the future before his wife gives birth, of course." | Contributed

What's more, Captain Sam Vimes is getting married and retiring from the Watch. For good. Which is a shame, because no one knows the streets of Ankh-Morpork or its criminal underworld better than him.
