Also known as “Sir Terence David John Pratchett, OBE” Terry Pratchett is one of my favourite authors. His Discworld series is wonderful.
His first book The Carpet People, was published in 1971, and since his first Discworld novel (The Colour of Magic) was published in 1983, he has written two books a year on average. (wikipedia)
You’ll also need to pay a visit to L-Space if you are a Pratchett fan.
In 2015 on the 12th March Terry Pratchett died, at home, with his family & cat, aged 66.
