The Long Earth [Kindle Edition]

4 1/2 stars.

The Long Earth is the first of a planned trilogy by Terry Pratchett and Stephen Baxter. If you were looking for two of the most unlikely authors to collaborate, you'd be hard pressed to choose better candidates than these.

Pratchett, as pretty much the entire world knows, predominantly writes humorous fantasy, and while it's true that his work has evolved from its beginnings as pure humor to take a much deeper, more profound look at the world through the medium of fantasy, his major appeal is still the humor.

Baxter, on the other hand, is the hardest of hard science fiction authors. His books are meticulously researched, and his speculation is firmly rooted in bleeding edge science. Like Pratchett, Baxter has evolved, in his case to include more believable, rounded characters with real stories. But when you approach a Baxter book you do so for the science fiction. (Even in his alternate history Northland series, Baxter follows the logic of his premise with a sharp, unyielding, scientific focus.)

If you approach The Long Earth expecting to find something matching either Pratchett's or Baxter's usual output, you are going to be coming at it all wrong. This is a genuine collaboration, and between them they have produced something quite different from their normal works.

In the year 2015, mankind suddenly discovers the existence of possibly infinite alternate worlds, differing only marginally (but progressively, the further out they are) from our own, which can be reached by the means of an electronic device that anyone can easily assemble. But there is one thing that is different about all of these worlds: humanity hasn't evolved on any of them.

The Long Earth explores the consequences of this discovery, and follows the exploration by Joshua Valienté, a "natural stepper", who can cross rapidly between worlds without aid of a device, and Lobsang, an AI who claims to be the reincarnation of a Tibetan motorcycle repairman.

The thing The Long Earth most reminded me of was Philip José Farmer's Riverworld, with its exploration of the unknown, mysterious new world the characters now find themselves in, and the overarching questions of what it all means and what it's for. And that's pretty good company for the book to find itself in.

There are one or two places where it seemed clear to me that either Pratchett or Baxter was responsible for a passage, but remarkably, in most of the book, you really couldn't tell, and that's a pretty impressive achievement for two such distinctive writers.

Most of the criticism I've seen about this book seems to come down to people expecting to read something just like Discworld and then being unhappy that it wasn't. It isn't supposed to be. It's very much its own book, and it's all the better for it.

Expect imaginative, accessible science fiction with a sense of wonder and a light touch, and that's exactly what you'll get in The Long Earth.

Long time Pratchett fan, I bought this to read on holiday, but found it quite heavy going. I didn't find enough of Terry's humour, which is my main reason for reading his stuff, and his strategy for sneaking subversive ideas into his reader's heads. The whole tone is much more Stephen Baxter, where, even when describing some great triumph of humanity he gives me the distinct impression that it will not be a good thing for the Universe. The main disappointment for me is that none of the main characters seem to develop as a result of their experiences. During the whole narrative we are waiting for some important revelation; the Traveller is a useful plot device, but is hardly the "Meaning of life, the Universe and Everything". I got the impression that a sequel may have been intended, but I'll not have any problem waiting.

Like most of the reviewers, I looked forward to this collaboration of two of the greats of sci fantasy. Now I have finished the book I am in two minds as to what to think of it.

One the one hand, it starts off with a good premise and two promisingly individualistic characters. Locations are well described and it gets off to a good start. On the other, once you get into the third chapter it just meanders along going nowhere very much and just as it seems to be picking up speed and getting really interesting..it ends. It doesn't quite say "To be continued", but it might as well.

I could have done with fewer tediously idyllic or uneventful alternate earths and more characterisation and action. For Pratchett the style is closer to "Nation" than Discworld. This is no bad thing - Nation is a great book, but the main "human" hero - Joseph Valiente - is downright boring. Lobsang has a lot of potential to be truly fascinating but after a few quirks of humour in the beginning, he fades into the background to become an annoyingly omniscient presence. Yes I am going to buy the inevitable follow up, but I have a feeling that I'll be disappointed. I hope I am wrong.
