An ancient Greek story of a shepherd's quest for a utopian city in the clouds becomes the unlikely thread connecting lives across centuries. In fifteenth-century Constantinople, an orphan girl named Anna discovers the last known copy of this tale within the city walls as a great army gathers to lay siege. In present-day Idaho, an octogenarian and former prisoner of war, Zeno, directs a group of children in a theatrical adaptation of the same story inside a public library, unaware that a troubled teenage idealist has planted a bomb among the shelves. Far in the future, Konstance, a girl who has never set foot on Earth, travels aboard an interstellar ship with only her father's retelling of the shepherd's journey to connect her to a past she cannot imagine.
This is a story about the resilience of the human heart and the transcendent power of the written word. It follows the journey of a single book as it travels through time, offering solace and hope to dreamers and outsiders in their darkest hours. Each character, though separated by vast gulfs of time and experience, finds their world imperiled and their life shaped by this one enduring narrative. The novel explores how stories survive, linking past, present, and future, and ultimately serves as a testament to our interconnectedness and the stewardship of books, the planet, and our capacity for compassion.
