« Night Watch » Terry Pratchett

One moment Sir Sam Vimes is in his old–patrolman form, chasing a sweet–talking psychopath across the rooftops of Ankh–Morpork.

The next, he’s lying naked in the street, having been sent back thirty years, courtesy of a group of time–manipulating monks who won’t leave well–enough alone.

This city is a dark place that Vimes remembers all too well — three decades before his title, fortune, beloved wife, and child on the way. Worse still, the murderer he’s pursuing has been transported back with him.

And on top of that — it’s the eve of a fabled street rebellion that killed a few good (and not so good) men. Sam Vimes knows his duty, and by changing history he might just save some worthwhile necks — though it could cost him his own personal future.

Plus there’s a chance to steer a novice watchman straight and teach him a valuable thing or three about policing — an impressionable young copper named Sam Vimes.
