Carcer's got everything he needs to control the Noble Dragon and destroy Ankh-Morpork. With hysteria on the streets and DEATH preparing himself for a very busy day, can The Watch, this band of misfits, step up and save the city from annihilation?

Sam Vimes wakes up into an alternate universe where he's a prisoner in the middle of a jailbreak; in Ankh-Morpork, the alternate-version of Vimes is leading The Watch straight into Carcer's trap.

In the race to obtain the second artifact, Cheery, Angua and Carrot venture into the Mines of Tak, where Cheery must confront the darkness in her past; meanwhile, Vimes and Sybil defend the Watch House from Doctor Cruces and her Assassins.

The Watch must trek through the Unreal Estate to destroy the sword in a magical lake.

Carcer is willing to do anything to find the sword for Gawain; the Watch is close on his tail, following him to Twilight Canyons, a place where the elderly residents await death; death patiently waits for them to draw their last breaths.

The Watch must rob the city's most secretive and dangerous institution in a desperate effort to find the magical artifact known as Gawain.

Using the policing know-how of Constable Carrot, the Watch connects Carcer's evil plan to strange goings-on at the magical institution called Unseen University. Perhaps a missing library book has something to do with the dragon attacks in the city.

Captain Sam Vimes' life in the City Watch is changed forever when an impossible figure from his past returns to Ankh-Morpork. 20 years ago, Vimes watched his street brother and gang-leader Carcer Dun fall from a fatal height. Somehow, Carcer is back.
