Rupert Wong and the Ends of the Earth [EPUB ebook] 

For a man who started a celestial war, Rupert Wong, Seneschal of Kuala Lumpur and indentured cannibal chef, isn’t doing too badly for himself. Sure, his flesh-eating bosses inexplicably have him on loan to the Greek pantheon, the very gods he thrust into interethnic conflict. Sure, the Chinese Hells have him under investigation for possible involvement in the fracas. And sure as hell, he’s already elbow-deep in debt with the Sisyphean gambling ring. But Rupert is alive. For now.Really, it could be slightly worse.
