The new Discworld novel is Snuff.
From Pratchett's Q & A with the Independent:
Read the complete Q & A.Choose a favourite author and say why you admire her/him
A favourite since my teens has been the late Paul Jennings, who used to have a slot in the 'Observer'. I think I admire him because of the curious lopsided but delightful way he looked at the world.

What fictional character most resembles you?
James Dixon as in 'Lucky Jim' by Kingsley Amis. Failing that, Rincewind [from Discworld].

Who is your hero/heroine from outside literature?
Kneejerk? Nelson Mandela. But I like the guys who change the world from their sheds, like James Dyson and Clive Sinclair.
