The follow-up to Terry Pratchett and Stephen Baxter's New York Times bestseller, The Long Earth, The Long War follows heroes Joshua and Lobsang as humankind's expansion throughout all the Long Earth threatens the future of humanity itself. -- War has come to Long Earth. Humankind has spread across the new worlds opened up by stepping, which Joshua and Lobsang explored a mere decade ago. Now ''civilization'' flourishes, and fleets of airships link the multiple Earths through exploration, trade, and culture. 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.
