The dazzling new science fiction adventure from the extraordinary imaginations of Terry Pratchett and Stephen Baxter - the fourth novel in a collaborative series that has been hailed as 'sense-of-wonder SF at its best' (Independent on Sunday).

"There's plenty of fun to be had from this ... a hymn to the joys of unfettered world-building ... but if the pace of plotting is gentle, the restless inventiveness more than compensates." -- Adam Roberts GUARDIAN "Rich in an awe-inspiring sense of wonder, with mind-boggling concepts thrown out like sparks from a Catherine wheel." -- Barry Forshaw INDEPENDENT "A triumph ... brings fresh and exciting concepts to an SF staple (paralell worlds) while keeping credible human characters at their heart ... as testament both to the diversity of Sir Terry Pratchett's writing, and the skill of Stephen Baxter's, The Long Earth series deserves a place on the bookshelves of hardcore SF fans and general readers alike." -- David Barnett INDEPENDENT ON SUNDAY "The Long Earth novels are beautifully visual and wittily imagined ... The Long Utopia ... serves to remind us just how bewitching and rich this series is, how beautiful is its writing, and vivid its imagination." FOR WINTER NIGHTS "There's the sense of two enviably talented writers having fun as they play in an infinite fictional universe." -- Jonathan Wright SFX
