This is book number 14 in the Discworld series.
It's a dreamy midsummer's night in the Kingdom of Lancre. But music and romance aren't the only things filling the air. Magic and mischief are afoot, threatening to spoil the royal wedding of King Verence and his favorite witch, Magrat Garlick. Invaded by some Fairie Trash, soon it won't be only champagne that's flowing through the streets . . .

His young adult novel, The Amazing Maurice and His Educated Rodents, won the Carnegie Medal, and Where's My Cow?, his Discworld book for “readers of all ages,” was a New York Times bestseller. His novels have sold more than seventy five million (give or take a few million) copies worldwide. Named an Officer of the British Empire “for services to literature,” Pratchett lived in England. He died in 2015 at the age of sixty-six.
