Unseen Academicals (Discworld #37)
The wizards at Ankh-Morpork's Unseen University are renowned for many things—wisdom, magic, and their love of teatime—but athletics is most assuredly not on the list. And so when Lord Vetinari, the city's benevolent tyrant, strongly suggests to Archchancellor Mustrum Ridcully that the university revive an erstwhile tradition and once again put forth a football team composed of faculty, students, and staff, the wizards of UU find themselves in a quandary. To begin with, they have to figure out just what it is that makes this sport—soccer with a bit of rugby thrown in—so popular with Ankh-Morporkians of all ages and social strata. Then they have to learn how to play it. Oh, and on top of that, they must win a football match without using magic.
Meanwhile, Trev (a handsome street urchin and a right good kicker) falls hard for kitchen maid Juliet (beautiful, dim, and perhaps the greatest fashion model there ever was), and Juliet's best pal, UU night cook Glenda (homely, sensible, and a baker of jolly good pies) befriends the mysterious Mr. Nutt (about whom no one knows very much, including Mr. Nutt, which is worrisome . . .). As the big match approaches, these four lives are entangled and changed forever. Because the thing about football—the most important thing about football—is that it is never just about football.
