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 . . .

The dazzling new science fiction adventure from the extraordinary imaginations of Terry Pratchett and Stephen Baxter - the fourth novel in a collaborative series that has been hailed as 'sense-of-wonder SF at its best' (Independent on Sunday).

Reviews
There's plenty of fun to be had from this . . . a hymn to the joys of unfettered world-building . . . but if the pace of plotting is gentle, the restless inventiveness more than compensates. -- Adam Roberts * GUARDIAN *
Rich in an awe-inspiring sense of wonder, with mind-boggling concepts thrown out like sparks from a Catherine wheel. -- Barry Forshaw * INDEPENDENT *
A triumph . . . brings fresh and exciting concepts to an SF staple (paralell worlds) while keeping credible human characters at their heart . . . as testament both to the diversity of Sir Terry Pratchett's writing, and the skill of Stephen Baxter's, The Long Earth series deserves a place on the bookshelves of hardcore SF fans and general readers alike. -- David Barnett * INDEPENDENT ON SUNDAY *
The Long Earth novels are beautifully visual and wittily imagined . . . The Long Utopia . . . serves to remind us just how bewitching and rich this series is, how beautiful is its writing, and vivid its imagination. * FOR WINTER NIGHTS *
There's the sense of two enviably talented writers having fun as they play in an infinite fictional universe. -- Jonathan Wright * SFX *
