His spectacular inventiveness makes the Discworld series one of the perennial joys of modern fiction.Mail on Sunday (UK)

An invasion of elves threatens to disrupt a perfectly dreamy Midsummer Night in the Discworldand throws the world of the witches into chaos in this cheeky tale from internationally bestselling author Sir Terry Pratchett.

On an incandescent Midsummer Night in the Kingdom of Lancre, the Discworld celebrates the wedding of King Verence and his favorite witch, Margrat Garlick. But music and romance arent the only things filling the air. Magic and mischief are afoot, threatening to spoil the festivities. On this special night dreams are especially powerfulstrong enough to break down the walls between realities. And some things you really dont want coming through and crashing a good party. Like elves.

Most of the denizens in the Discworld have forgotten what life was like with the elves around. But Granny Weatherwax, Nanny Ogg, and Magrat Garlick remember. Even in a world of wizards, trolls, dwarvesand the odd orangutanthese pernicious fairies are particularly nasty. The witches know that if the elves arent driven back to the other side, it wont only be champagne flowing through the streets.
