Our Lady of Darkness

Middle-aged San Francisco horror writer Franz Westen is rediscovering ordinary life following a long alcoholic binge. Then one day, peering at his apartment window from atop a nearby hill, he sees a pale brown thing lean out his window…and wave.
This encounter sends Westen on a quest through ancient books and modern streets, for the dark forces and paramental entities that thrive amidst the towering skyscrapers of modern urban life…and meanwhile, the entities are also looking for him.
