The Long Utopia

544 pages

A vast, contemplative journey across infinite worlds that ultimately asks what it means to live a single, fragile human life.

What it feels like

Reading this novel feels like standing on the edge of an infinite frontier while quietly reflecting on the passage of time. The narrative unfolds at a steady, deliberate pace, balancing the mind-bending scale of parallel universes with the intimate, often melancholic struggles of its aging protagonists. There is an elegiac undercurrent to the prose, blending hard-science conceptualizing with a warm, wry humanism that softens the existential dread of cosmic insignificance. It is a deeply contemplative experience, shifting seamlessly from quiet moments of personal discovery—an AI seeking a normal life, a man searching for his roots—to awe-inspiring encounters with alien ecologies. This will delight readers who crave big-idea science fiction that remains firmly anchored by its compassionate, character-driven heart.

About the book

Lobsang's pursuit of a human life, Joshua's search for his father and the adaptation efforts of "the Next" post-humans are challenged by a voracious alien race that would conquer and colonize the Long Earth.

"2045-2059. Human society continues to evolve on Datum Earth, its battered and weary origin planet, as the spread of humanity progresses throughout the many Earths beyond. Lobsang, now an elderly and complex AI, suffers a breakdown, and disguised as a human attempts to live a 'normal' life on one of the millions of Long Earth worlds. His old friend, Joshua, now in his fifties, searches for his father and discovers a heretofore unknown family history. And the super-intelligent post-humans known as 'the Next' continue to adapt to life among 'lesser' humans. But an alarming new challenge looms. An alien planet has somehow become 'entangled' with one of the Long Earth worlds and, as Lobsang and Joshua learn, its voracious denizens intend to capture, conquer, and colonize the new universe--the Long Earth--they have inadvertently discovered. World-building, the intersection of universes, the coexistence of diverse species, and the cosmic meaning of the Long Earth itself are among the mind-expanding themes explored in this exciting new installment of Terry Pratchett and Stephen Baxter's extraordinary Long Earth series" --
