A house with endless halls, crumbling statues, and an ocean trapped within its walls. This is Piranesi’s world, a labyrinth both beautiful and treacherous. He is its lone inhabitant – except for the mysterious Other, who seeks knowledge within its depths. But when messages appear, whispering of another reality, Piranesi’s world fractures. Is the House his home, or is it something more sinister? As forgotten truths resurface, Susanna Clarke weaves a tale of mystery, memory and the search for what lies in the unknown.
