Unseen Academicals, by Terry Pratchett (2009, UK)

Disk world. Mr Nutt arrives at the Unseen University and begins working there. He knows EVERYTHING. He's very kind. He's got worth. But he's an orc, although he doesn't know. It's all about the wizards playing the old foot the ball, Glenda that's wise and runs the Night Kitchen, Trevor who lits the candles, Juliet, who shines, the big football match. And Nutt gaining worth. Deep and hilarious.
