The Long Earth

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 finds 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 an infinity of new worlds. All it takes is a single step. . . .
