Sir Terry Pratchett left us, far too early, in March 2015. To celebrate his life and works, we've given over the 2017 Discworld Diary - which will be a perennial diary - to remembrances and tributes from some of those who knew and loved him and his extraordinary body of work. Contributors include Neil Gaiman, A S Byatt, Terry Pratchett's literary agent Colin Smythe, co-author of the Long Earth books Stephen Baxter, famed bookseller Rog Peyton, and many more.

With an introduction from his daughter Rhianna Pratchett and an afterword from longtime friend and colleague Rob Wilkins.

Sir Terry Pratchett is a publishing phenomenon. Among his many prizes and citations are the World Fantasy Life Achievement Award, the Carnegie Medal, the BSFA Award, eight honorary doctorates and, of course, a knighthood. In 2012, he won a BAFTA for his documentary on the subject of assisted suicide, 'Terry Pratchett: Choosing to Die'. He is the author of fifty bestselling books but is best known for the globally renowned Discworld series.

The first Discworld novel, The Colour of Magic, was published in 1983, and the series is still going strong almost three decades later. Four Discworld novels - Hogfather, Going Postal, The Colour of Magic and The Light Fantastic - have been adapted for television, with more to follow. His books have sold approximately 85 million copies worldwide (but who's counting?), and been translated into forty languages.

In 2007, Terry Pratchett was diagnosed with early onset Alzheimer's Disease. He died in 2015.
