Temper

The protagonist of Temper, Auben Mtuze, is literally an evil twin. His brother Kasim was born with six out of seven possible virtues, and only one of the seven vices. Which means Auben has six vices, an almost-unheard-of number that marks him for poverty and disdain in a world where the good and the bad are neatly separated by walls between their respective neighborhoods.
