From the New York Times bestselling author of Jonathan Strange & Mr. Norrell, Susanna Clarke delivers an intoxicating, hypnotic new novel set in a dreamlike alternative reality with Piranesi.

Piranesi's house is no ordinary building; its rooms are infinite, its corridors endless, its walls are lined with thousands upon thousands of statues, each one different from all the others. Within the labyrinth of halls, an ocean is imprisoned; waves thunder up staircases, rooms are flooded in an instant. But Piranesi is not afraid; he understands the tides as he understands the pattern of the labyrinth itself. He lives to explore the house.

There is one other person in the house--a man called The Other, who visits Piranesi twice a week and asks for help with research into A Great and Secret Knowledge. But as Piranesi explores, evidence emerges of another person, and a terrible truth begins to unravel, revealing a world beyond the one Piranesi has always known.

After receiving a frantic letter from her newly-wed cousin begging for someone to save her from a mysterious doom, Noemí Taboada heads to High Place, a distant house in the Mexican countryside. She's not sure what she will find—her cousin's husband, a handsome Englishman, is a stranger, and Noemí knows little about the region.

Noemí is also an unlikely rescuer: She's a glamorous debutante, and her chic gowns and perfect red lipstick are more suited for cocktail parties than amateur sleuthing. But she's also tough and smart, with an indomitable will, and she is not afraid: Not of her cousin's new husband, who is both menacing and alluring; not of his father, the ancient patriarch who seems to be fascinated by Noemí; and not even of the house itself, which begins to invade Noemí's dreams with visions of blood and doom.

Her only ally in this inhospitable abode is the family's youngest son. Shy and gentle, he seems to want to help Noemí, but might also be hiding dark knowledge of his family's past. For there are many secrets behind the walls of High Place. The family's once colossal wealth and faded mining empire kept them from prying eyes, but as Noemí digs deeper she unearths stories of violence and madness.

And Noemí, mesmerized by the terrifying yet seductive world of High Place, may soon find it impossible to ever leave this enigmatic house behind.
