The thrilling conclusion to the internationally bestselling Long Earth series explores the greatest question of all: What is the meaning of life?

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 hyper-intelligent post-humans--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.

Meanwhile, on a trek in the High Meggers, Joshua Valienté, now nearing seventy, is saved from death when a troll band discovers him. Living among the trolls as he recovers, Joshua develops a deeper understanding of this collective-intelligence species and its society. He discovers that some older trolls, with capacious memories, act as communal libraries, and live on a very strange Long Earth world, in caverns under the root systems of trees as tall as mountains.

Valienté also learns something much more profound... about life and its purpose in the Long Earth: We cultivate the cosmos to maximize the opportunities for life and joy in this universe, and to prepare for new universes to come.

It causes riots and religions. It has people dancing in the streets and leaping off skyscrapers. And it's all because of the impenetrable gray shield that slid into place around the solar system on the night of November 15, 2034.

Some see the bubble as the revenge of an insane God. Some see it as justice. Some even see it as protection. But one thing is for certain -- now there is the universe, and the earth. And never the twain shall meet.

Or so it seems. Until a bio-enhanced PI named Nick Stavrianos takes on a job for an anonymous client: find a girl named Laura who disappeared from a mental institution by the most direct possible method -- walking through the walls.

Prisoner of New Half-Way Tree

It's Carnival time and the Caribbean-colonized planet of Toussaint is celebrating with music, dance, and pageantry. Masked "Midnight Robbers" waylay revelers with brandished weapons and spellbinding words. But to young Tan-Tan, the Robber Queen is simply a favorite costume to wear at the festival -- until her power-corrupted father commits an unforgivable crime.

Suddenly, both father and daughter are thrust into the brutal world of New Half-Way Tree. Here monstrous creatures from folklore are real, and the humans are violent outcasts in the wilds. Here Tan-Tan must reach into the heart of myth -- and become the Robber Queen herself. For only the Robber Queen's legendary powers can save her life... and set her free.

Only a few know the terrifying truth--an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun. They know the truth--but who will listen? They have foreseen the cost of abundant energy--but who will believe? These few beings, human and alien, hold the key to the Earth's survival.

The strange but beautiful purple blossoms now grew wild in his backyard. One day Brad Carter tripped and fell into an alternate world, a world peopled by these very flowers.

It's been a year since Binti and Okwu enrolled at Oomza University. A year since Binti was declared a hero for uniting two warring planets. A year since she found friendship in the unlikeliest of places.

And now she must return home to her people, with her friend Okwu by her side, to face her family and face her elders.

But Okwu will be the first of his race to set foot on Earth in over a hundred years, and the first ever to come in peace.

After generations of conflict can human and Meduse ever learn to truly live in harmony?

World-hopping, high-action adventure starring a smart boy with computer skills and a tough girl who pilots a blimp

The airship Everness makes a Heisenberg Jump to an alternate Earth unlike any her crew has ever seen. Everett, Sen, and the crew find themselves above a plain that goes on forever in every direction without any horizon. There they find an Alderson Disc, an astronomical megastructure of incredibly strong material reaching from the orbit of Mercury to the orbit of Jupiter.

Then they meet the Jiju, the dominant species on a plane where the dinosaurs didn't die out. They evolved, diversified, and have a twenty-five million year technology head-start on humanity. War between their kingdoms is inevitable, total and terrible.

Everness has jumped right into the midst of a faction fight between rival nations, the Fabreen and Dityu empires. The airship is attacked, but then defended by the forces of the Fabreen, who offers theEverness crew protection. But what is the true motive behind Empress Aswiu's aid? What is her price?

The crew of the Everness is divided in a very alien world, a world fast approaching the point of apocalypse.

Marak has suffered the madness his entire life. He is a prince and warrior, strong and shrewd and expert in the ways of the desert covering his planet. In the service of his father, he has dedicated his life to overthrowing the Ila, the mysterious eternal dictator of his world. For years he has successfully hidden the visions that plague him -- voices pulling him eastward, calling Marak, Marak, Marak, amid mind-twisting visions of a silver tower. But when his secret is discovered, Marak is betrayed by his own father and forced to march in an endless caravan with the rest of his world's madmen to the Ila's city of Oburan.

Instead of death, Marak finds in Oburan his destiny, and the promise of life -- if he can survive what is surely a suicidal mission. The Ila wants him to discover the source of the voices and visions that afflict the mad. Despite the danger sof the hostile desert, tensions within the caravan, and his own excruciating doubts, Marak miraculously reaches his goal -- only to be given another, even more impossible mission by the strange people in the towers.

According to these beings who look like him yet act differently than anyone he has ever known, Marak has a slim chance to save his world's people from the wrath of Ila's enemies. But to do so, he must convince them all -- warring tribes, villagers, priests, young and old, as well as the Ila herself -- to follow him on an epic trek across the burning desert before the hammer of the Ila's foes falls from the heavens above.

It is the twenty-first century. Earth's space program is thriving, with a colony in place in the Moon. And then an incredible discovery is made on the lunar farside. A massive structure is being erected by living machines--microscopically small, intelligent, unstoppable, consuming whatever they touch. All who come near them die horribly. Meanwhile, the mysterious structure continues to grow, expand, take shape. And its creators begin to multiply....

Is this the first strike in an alien invasion from the stars? Or has human nanotech experimentation gone awry, triggering a long-predicted disaster? As riots rage across a panicked Earth, scientists on Earth and on the Moon race to learn the truth before humanity's home is engulfed by the voracious machines and its inhabitants perish in the most terrifying plague ever known.
