Before his untimely death in 2015, Terry Pratchett had written over 70 books spanning novels, non-fiction, and collaborative works - selling upwards of 100 million copies in 43 languages.
He’s perhaps best known for 41 Discworld comic fantasy novels, the first of which was published in 1983, that display a dazzling talent for world-building and a wicked sense of humour.
Pratchettt also wrote the novel Good Omens alongside Neil Gaiman, which was recently turned into a popular television series starring Michael Sheen and David Tennant.
For most of his life Pratchett wrote an average of two books a year so, with so many to choose from, it’s hard for a Pratchett beginner to know where to begin.
