The Long Utopia is the fourth installment of The Long Earth Series written by Stephen Baxter and Terry Pratchett. It was first published in June, 2015.

The cover image as well as the planetary spin motor sketch inside the book were created by Richard Shailer.[1]


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.


Chapter 1

The year is 2036, and Cassie Poulson is a settler living in New Springfield, a town located in the High Meggers. She digs a cellar next to her house and accidentally discovers a cave, inside of which she glimpses a beetle-like creature. She doesn't tell anybody about the encounter, and covers up the hole.

About a decade later, Sister Agnes holds a party at the Home in Madison West 5, during which Lobsang apparantly suffers a fatal breakdown.

In 1848, Oswald Hackett and Luis Valienté meet, both who are natural Steppers.[2]
