The Long Earth

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 in the trees. Where have the mud, blood and blasted landcape of No Man's Land gone?

2015: Madison, Wisconsin. Cop Monica Jansson is exploring the burned-out home of a reclusive - some said mad, others dangerous - scientist when she finds a curious gadget: a box containing some wiring, a three-way switch and a...potato. It is the prototype of an invention that will change the way Mankind views his world for ever.

And that's an understatement if ever there was one...

The Long Earth is the first novel in an exciting new collaboration between the creator of Discworld Terry Pratchett and the acclaimed SF writer Stephen Baxter.
