“Their trademark world building and questions of morality remain intact . . . The explosive cliffhanger ending—also now something of a trademark—promises one final return to the series.” — Booklist

The fourth novel in Terry Pratchett and Stephen Baxter’s bestselling series, which io9 calls “a brilliant science fiction collaboration.”

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.

The complete list of books in the Long Earth series include:

Terry Pratchett (1948–2015) was the acclaimed creator of the globally revered Discworld series. In all, he authored more than fifty bestselling books, which have sold more than one hundred million copies worldwide. His novels have been widely adapted for stage and screen, and he was the winner of multiple prizes, including the Carnegie Medal. He was awarded a knighthood by Queen Elizabeth II for his services to literature in 2009, although he always wryly maintained that his greatest service to literature was to avoid writing any.



Stephen Baxter is an acclaimed, multiple-award-winning author whose many books include the Xeelee Sequence series, the Time Odyssey trilogy (written with Arthur C. Clarke), and The Time Ships, a sequel to H. G. Wells's classic The Time Machine. He lives in England.
