The Long Earth Books in Order

The Long Earth series, co-written by Terry Pratchett and Stephen Baxter, starts with a simple, world-tilting idea. A cheap device, built from everyday parts, lets almost anyone “step” sideways into an alternate version of Earth. There aren’t just a few alternates, there are millions, stretching out like an endless chain, each one a little different and most of them empty of people.

At first, that sounds like a gift: unlimited land, fresh resources, and a way to walk away from crowded politics. The economic shock is immediate, because land and borders stop meaning what they used to mean. But the series is less interested in the gadget than in what people do with it. As settlers move outward, new communities form, old governments try to keep control, and the definition of “home” starts to shift.

It’s a frontier story where the frontier never ends.

The books follow a small group of travellers who keep pushing west, away from the familiar world. Early on, that includes Joshua Valienté, a practical, stubborn explorer type, and Lobsang, a monk with a very unusual background. Their journeys turn into a kind of moving survey of the Long Earth, from improvised homesteads to strange experiments in how to live. Because stepping is so easy, the books also get to linger on the practical knock-on effects: mapping the unknown, moving supplies, and trying to enforce rules when distance stops behaving.

There’s plenty of adventure, but the tension often comes from questions you can’t solve with a gunfight. If anyone can leave, who stays behind to run the hospitals, farms, and power stations? If new worlds are “empty”, who decides that, and what happens when someone else disagrees? The Long Earth becomes a place where philosophy turns into policy very fast, and where even well-meaning decisions have knock-on effects.

The later books widen the lens even further, sending expeditions into deeper territory and following conflicts that spill across worlds. You’ll see the series explore discovery, fear, and the temptation to turn a vast frontier into a battlefield. It also keeps asking what “humanity” means when distance stops being measured in miles.

Every new world comes with a new argument.
