The Long Earth

The Western Front, 1916. Private Percy Blakeney wakes up. He is lying on fresh spring grass. He can hear birdsong, and the wind in the leaves in the trees. Where have the mud, blood, and blasted landscape of No Man's Land gone? Madison, Wisconsin, 2015. Cop Monica Jansson is exploring the burned-out home of a reclusive - some said mad, others dangerous - scientist when she finds a curious gadget: a box containing some wiring, a three-way switch and a potato. It is the prototype of a life-changing invention....

A generation after the events of The Long Earth, mankind has spread across the new worlds opened up by Stepping. Where Joshua and Lobsang once pioneered, now fleets of airships link the stepwise Americas with trade and culture. Mankind is shaping the Long Earth - but in turn the Long Earth is shaping mankind...

The years 2040 - 2045: After the cataclysmic Yellowstone eruption, there is massive economic dislocation as populations flee Datum Earth to myriad Long Earth worlds. Sally, Joshua, and Lobsang are all involved in this perilous work when, out of the blue, Sally is contacted by her long-vanished father and inventor of the original Stepper device, Willis Linsay. He tells her he is planning a fantastic voyage across the Long Mars and wants her to accompany him. But Sally soon learns that Willis has ulterior motives....

It's 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 50s, searches for his father and discovers a heretofore unknown family history.

It's 2045-2059. After the cataclysmic upheavals of Step Day and the Yellowstone eruption humanity is spreading farther 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.

It's 2070-71. Nearly six decades after Step Day, a new society continues to evolve in the Long Earth. Now, a message has been received: "Join us." The Next - the hyperintelligent posthumans - realize that the missive contains instructions for kick-starting the development of an immense artificial intelligence known as The Machine. But to build this computer the size of an Earth continent, they must obtain help from the more populous and still industrious worlds of mankind.

It's 2070-71. Nearly six decades after Step Day, and in the Long Earth the new Next posthuman society continues to evolve. For Joshua Valienté, now in his late 60s, it is time to take one last solo journey into the High Meggers: an adventure that turns into a disaster. Alone and facing death, his only hope of salvation lies with a group of trolls. But as Joshua confronts his mortality, the Long Earth receives a signal from the stars.
