The long utopia | terry pratchett

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 .
