Food of the Gods

"By day, Rupert Wong - sorcerer, chef, former triad - prepares delicious meals of human flesh for a dynasty of ghouls in Kuala Lumpur ; by night, he's an administrator for the Ten Chinese Hells. It's a living, of sorts. When the Dragon of the South demands that Rupert investigate the murders of his daughter and her mortal husband, Rupert is caught in a war between gods that's as bewildering as it is bloody. If he's going to survive, he'll need to stay sharp, stay lucky, and always read the fine print..." --Page 4 of cover.
