As I recall, the editor of Olympus wanted stories where we wrote the ancient gods living in a modern world. I'd already done exactly that in Summon the Keeper, but was willing to rise to the challenge of doing it again. Differently. The great thing about the ancient gods is that once you've done the research and accepted all the mythic information as fact, you realize that the Power and the Presence are just window dressing; they're really nothing more than a highly dysfunctional family.
