“The Long Earth is a brilliant Science Fiction collaboration with Stephen Baxter: a love letter to all Pratchett fans, readers, and lovers of wonder everywhere. . . . This novel is a gift to be shared with anyone who loves to be amazed.” - Io9
“As you’d expect from these authors, the writing is elegant and witty, peppered with sly pop-culture references. The worlds of the Long Earth are all richly rendered, and even the walk-on characters are deftly imagined. . . . The Long Earth is a genuinely thoughtful and entertaining exploration of a profoundly changed universe-and the potential seems endless not just for the characters, but for Pratchett and Baxter as well.” - Tor.com
“ The Long Earth is the solid start of a series with infinite potential.” - Shelf Awareness
“Stay tuned for the next episode of a very old-fashioned sf quest yarn (think Jules Verne and 2001) that, since Pratchett is involved, is crammed with scientifically informed amusement.” - Booklist
“In this thought-provoking collaboration, Pratchett (the Discworld series) and Baxter (Stone Spring) create an infinity of worlds to explore. . . fascinating premise.” - Publishers Weekly
