The fantastic third book in Terry Pratchett and Stephen Baxter’s collaborative science fiction series!
2040-2045: In the years after the cataclysmic Yellowstone eruption there is massive economic dislocation as populations flee Datum Earth to myriad Long Earth worlds. Sally, Joshua, and Lobsang are all involved in this perilous work when, out of the blue, Sally is contacted by her long-vanished father and inventor of the original Stepper device, Willis Linsay. He tells her he is planning a fantastic voyage across the Long Mars and wants her to accompany him. But Sally soon learns that Willis has ulterior motives. Meanwhile U. S. Navy Commander Maggie Kauffman has embarked on an incredible journey of her own, leading an expedition to the outer limits of the far Long Earth.
The world-building finesse of Stephen Baxter and the parodic humour of Sir Terry Pratchett collide once again in an adventure that spans many worlds with intrigue, wit and wisdom.
