I just finished Unseen Academicals by Terry Pratchett, the latest in his Discworld novels.

Unseen Academicals covers the worlds of sports, in particular the Ankh-Morpork sport of "football", as it changes from an ultra-violent mob game to a slightly less violent approved game.  It also introduces a new race to the Discworld, the orc.  The usual Pratchett twist is that the orc in question is a fine, upstanding person rather than a vicious killer.

Another nice, enjoyable book from Pratchett.  This one focuses on mainly new characters, rather than being part of an existing series of regulars.
