The Long Earth (Amazon, Kobo)

The possibilities are endless. (Just be careful what you wish for. . . .) 

1916: The Western Front. Private Percy Blakeney wakes up. He is lying on fresh spring grass. He can hear birdsong and the wind in the leaves. Where have the mud, blood, and blasted landscape of no-man's-land gone? For that matter, where has Percy gone? 

2015: Madison, Wisconsin. Police officer Monica Jansson is exploring the burned-out home of a reclusive-some say mad, others allege dangerous-scientist who seems to have vanished. Sifting through the wreckage, Jansson find a curious gadget: a box containing some rudimentary wiring, a three-way switch, and . . . a potato. It is the prototype of an invention that will change the way humankind views the world forever. 

The first novel in an exciting new collaboration between Discworld creator Terry Pratchett and the acclaimed SF writer Stephen Baxter, The Long Earth transports readers to the ends of the earth-and far beyond. All it takes is a single step. . . .

Humankind is shaping the Long Earth, but in turn the Long Earth is shaping humankind. A new America that has christened itself "Valhalla" has emerged more than a million steps from the original Datum Earth. And like the American revolutionaries of old, the Valhallans resent being controlled from afar by the Datum government. 

In the intervening years, the song of the trolls—graceful, hive-mind humanoids—has suffused the Long Earth. But in the face of humankind's inexorable advance, they are beginning to fall silent . . . and gradually disappear. 

Joshua, now married and a father, is summoned by Lobsang. It seems that he alone can confront the perfect storm of crises that threatens to plunge all of the Long Earth into war.A war unlike any that has been waged before...
