The Long Utopia

The Long Earth, Book 4

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.

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.

To counter this threat will require the combined efforts of humankind, machine and the superintelligent Next. And some must make the ultimate sacrifice....
