To Reign in Hell

""All right, old friend," said the other. "I'll stay the night. Have you brandy?" Yaweh nodded. They both stood at once, as if a hidden message had come to them, and embraced. "I don't see you often enough," said Yahweh. "Heaven has grown too large," said Satan."

To Reign in Hell is a 1984 fantasy novel by Steven Brust that retells the story of Yahweh's creation of Heaven and Earth, and Satan's creation of Hell. It is notable for its simple, yet compelling cosmology, its witty use of language, and its depiction of the War in Heaven as an avoidable catastrophe that was tragic for all concerned.
