2045-2059. After the cataclysmic upheavals of Step Day and the Yellowstone eruption humanity is spreading further into the Long Earth, and society, on a battered Datum Earth and beyond, continues to evolve.
Now an elderly and cantankerous AI, Lobsang lives in disguise with Agnes in an exotic, far-distant world. He's convinced they're leading a normal life in New Springfield - they even adopt a child - but it seems they have been guided there for a reason. As rumours of strange sightings and hauntings proliferate, it becomes clear that something is very awry with this particular world.
Millions of steps away, Joshua is on a personal journey of discovery: learning about the father he never knew and a secret family history. But then he receives a summons from New Springfield. Lobsang now understands the enormity of what's taking place beneath the surface of his earth - a threat to all the worlds of the Long Earth.
To counter this threat will require the combined efforts of humankind, machine and the super-intelligent Next. And some must make the ultimate sacrifice . . .
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*.
