Lyn Pratchett Book order (chronological)

Some night-time prowler is turning the citizens of Ankh-Morpork, greatest city of the fantasy Discworld, into something resembling small charcoal biscuits. And that's a real problem for Captain Vimes of the City Watch, who must tramp the mean streets of the city searching for a seventy-foot-long fire-breathing dragon which, he believes, can help him with their enquiries. In a city thrown into turmoil by magic, charcoal biscuits, secret societies and mad lady dragon breeders ("Just tell him 'sit' if he'sothering you"), he's just looking for the facts

This is the story of Jekub, the Dragon in the Hill with great big teeth and a great loud voice. (Well, that’s according to the nomes, but they are only four inches tall.) When humans threaten their new home in the quarry, the natural thing would be to run and hide. But the nomes have got the wild idea that they should fight back. After all, everyone knows that nomes are faster and smarter than humans, and now they have a secret weapon . . . The fantastically funny second book of the nomes, from the author of the bestselling Discworld series.
