I'm more into the cosmopolitans like Stuart Cloete (Turning Wheels, Rags of Glory) and the disruptors with novel ideas like Etienne Leroux* (Sewe dae by die Silbersteins, a hilarious and controversial novel of miscegenation -- for which description I was fired from the SABC for the first, but not the last, time, which was notable and amusing since I didn't actually have a job there -- I was still at school). It's no accident that Etienne was from my hometown, Oudtshoorn; the town produced a veritable who's who of the arts and politics. The most readable, involving and amusing South African novelist (after me, of course) is Peter Temple, another cosmopolitan, several of whose books are set in Melbourne, a city I know well. Of course, all of that is given on the assumption that, like most of the rest of the useful intelligentsia, your preferred reading matter is well-crafted and characterised thrillers.
* Not that Cloete isn't also a disruptor; you can see people in my mother's family, whose ancestors were on the Great Trek, raising their blood pressure visibly when Turning Wheels is mentioned.
