'Don't put your trust in revolutions. They always come round again. That's why they're called revolutions. People die, and nothing changes.'

For a policeman, there can be few things worse than a serial killer at loose in your city. Except, perhaps, a serial killer who targets coppers, and a city on the brink of bloody revolution. The people have found their voice at last, the flags and barricades are rising...And the question for a policeman, an officer of the law, a defender of the peace, is:

Are you with them, or are you against them?

Born Terence David John Pratchett, Sir Terry Pratchett sold his first story when he was thirteen, which earned him enough money to buy a second-hand typewriter. His first novel, a humorous fantasy entitled The Carpet People, appeared in 1971 from the publisher Colin Smythe.

Terry worked for many years as a journalist and press officer, writing in his spare time and publishing a number of novels, including his first Discworld novel, The Color of Magic, in 1983. In 1987, he turned to writing full time.

There are over 40 books in the Discworld series, of which four are written for children. The first of these, The Amazing Maurice and His Educated Rodents, won the Carnegie Medal.

A non-Discworld book, Good Omens, his 1990 collaboration with Neil Gaiman, has been a longtime bestseller and was reissued in hardcover by William Morrow in early 2006 (it is also available as a mass market paperback - Harper Torch, 2006 - and trade paperback - Harper Paperbacks, 2006).

In 2008, Harper Children's published Terry's standalone non-Discworld YA novel, Nation. Terry published Snuff in October 2011.

Regarded as one of the most significant contemporary English-language satirists, Pratchett has won numerous literary awards, was named an Officer of the British Empire (OBE) “for services to literature” in 1998, and has received honorary doctorates from the University of Warwick in 1999, the University of Portsmouth in 2001, the University of Bath in 2003, the University of Bristol in 2004, Buckinghamshire New University in 2008, the University of Dublin in 2008, Bradford University in 2009, the University of Winchester in 2009, and The Open University in 2013 for his contribution to Public Service.

In Dec. of 2007, Pratchett disclosed that he had been diagnosed with Alzheimer's disease. On 18 Feb, 2009, he was knighted by Queen Elizabeth II.
