Terry Pratchett’s Snuff is one of the fastest-selling novels in history after just three days on sale. UK booksellers have sold more than 54,000 copies of Pratchett’s 39th Discworld novel, according to The Bookseller Magazine. It’s the fastest selling hardback since Dan Brown’s The Lost Symbol in 2009.

AbeBooks still has a few signed copies available.

Demand for Pratchett’s work is remarkable. The Discworld series became with The Colour of Magic in 1983 when Mrs Thatcher was the UK’s prime minister and Ronald Reagan was soon to become US president.
