From the author of Smilla's Sense of Snow comes this highly imaginative novel, In a Danish feudal castle, 1520, a count believes he has pinpointed the center of the universea patch of land on his estate. But when his discovery is met with disbelief, he walls off his mansion and has all of the clocks stopped. Four centuries pass instantaneously, and the count's young secretary, Carl, emerges from isolation to find a world bursting with war, innovation, love, sexuality, danger, and all the values of the sixteenth century turned upside down as though by supernatural forcesnamely, the force of history. From one of our most gifted international writers comes a dazzling epic fairy tale, a tough fable about the gifts and iniquities of progress.
