Terry's new book 'Unseen Academicals' was released recently
Wiltshire-based fantasy author Sir Terry Pratchett's latest novel was published on 1 October.
Sir Terry is the acclaimed creator of the Discworld series which started more than 25 years ago.
'Unseen Academicals' is the 37th in the series.
Terry, who lives near Salisbury, also has Alzheimer's Disease and is barely able to type now. He has donated more than £1m to Alzheimer's charities since he was diagnosed.
His new book has a football theme to it as Terry explained: "The wizards of Unseen University have to play a game of football," he said.
"The more I thought about football and researched it, the more I realised that the important thing about football is that it's not just about football.
"It's about supporting your team, it's about the area where you grew up and the dynamic between people. That started to make it seem interesting for me."
Regarding his disease, Sir Terry believes it is vital to encourage more donations to fund research.
Scientists have warned that a severe shortage of brain donations is leading to major delays in the search for a cure or treatments for dementia.
Research has found only 31% of people in the UK realise you can donate your brain after death for research into the condition.
Sir Terry said: "As a disease, Alzheimer's costs the nation more than heart attacks, strokes and cancer put together.
"Examining the brains of sufferers helps a lot. They're certainly going to have my brain when I'm gone because it's about time somebody made use of it!"
