Terry Pratchett's new book has a title. It's called Dodger and is not a Discworld novel, instead being set in the same alterno-Victorian world as Nation.
The book will be published in September this year. Pratchett is also working on his autobiography and is planning the next Discworld novel, which will possibly be Raising Taxes, the conclusion to the Moist von Lipwig trilogy.
Pratchett's next-released book will The Long Earth, a collaboration with SF author Stephen Baxter, due on 21 June this year.
