In Houses of Ravicka, the city's comptroller, author of Regulating the Book of Regulations, seems to have lost a house. It is not where it's supposed to be, though an invisible house on the far side of town, which corresponds to the missing house, remains appropriately invisible. Inside the invisible house, a nameless Ravickian considers how she came to the life she is living, and investigates the deep history of Ravicka-that mysterious city-country born of Renee Gladman's philosophical, funny, audacious, extraordinary imagination.
