The fourth novel in Terry Pratchett and Stephen Baxter’s internationally bestselling “Long Earth” series, hailed as “a brilliant science fiction collaboration . . . a love letter to all Pratchett fans, readers, and lovers of wonder everywhere” (Io9).
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.
Sir Terence David John Pratchett, OBE more commonly known as Terry Pratchett, was an English novelist, known for his frequently comical work in the fantasy genre. He is best-known for his popular and long-running Discworld series of comic fantasy novels. Pratchett's first novel, *The Carpet People*, was published in 1971, and since his first Discworld novel (*The Colour of Magic*) was published in 1983, he has written two books a year on average. Pratchett was the UK's best-selling author of the 1990s, and as of December 2007 had sold more than 55 million books worldwide, with translations made into 36 languages. He is currently the second most-read writer in the UK, and seventh most-read non-US author in the US. In 2001 he won the Carnegie Medal for his young adult novel *The Amazing Maurice and his Educated Rodents*.
