Turn-of-the-century American architect John Drinkwater begins to suspect that within this world there lies another (and within that, another and another ad infinitum, each larger than the world that contains it). Towards the center is the realm of the fairies, which his wife, the Englishwoman Violet Bramble, can see and talk with but he can′t. Drinkwater gathers his thoughts into an ever-evolving book entitled "The Architecture of Country Houses", which goes through at least six ever longer and more mystical editions.
