The Dark Side of the Sun (playing on the title of Pink Floyd’s iconic 1973 album ‘The Dark Side of the Moon’, which to be fair makes a lot more sense) was first published in 1976, long before the Discworld series started with The Colour of Magic in 1983. It’s largely forgotten now, kept in print by Pratchett completists I suspect. It’s a fun, lightly sketched sci-fi adventure with numerous throw-away ideas. Fans of Pratchett’s later work will find references to Discworld jumping off the page every so often, which to be honest provided most of the entertainment.

The novel is really a mystery written in a lightly comic tone very reminiscent of Douglas Adams. Set far in the future the galaxy is populated by fifty-two different sentient species, all of which evolved in the last five million years. Scattered across space are artefacts of ‘the Jokers’ an apparently extinct race of master engineers who may or may not have been the reason life arose in the first place. The only surviving piece of Joker text is a poem which says they have gone to a new home “at the dark side of the sun”.
Dom Sabalos, the novel’s protagonist, sets out with his tutor, Hrsh-Hgn and his Man-Friday robot assistant, on a quest to find the Jokers world. As he travels to the various populated planets he is hunted by a robot assassin who keeps missing despite having good luck engineered into his programme. Something or someone wants Dom to survive to find the Jokers.
As a sci-fi story The Dark Side of the Sun is eminently forgettable. The science is so lightly sketched as to be closer to magic, and the characters are fairly one-dimensional. The ending is a bit baffling if I am honest. There are some clever ideas alongside quite a lot of clichéd characters and situations. But this will not matter to Discworld fans, who will find lots of points of comparison between this novel and the series. Hogswatchnight and Small Gods both first appear here, without much if any detail about what they are other than annual holidays or celebrations. This is very much in the style of Dark Side – not much detail is provided and the reader is left to fill in most of the gaps, making the novel an immersive experience as we build the world ourselves with the author acting as guide.
Sir Terry was famously progressive, way before his time (books and programmes from the 1990’s now often come with warnings that they represent ideas and terms that were commonly used at the time but now may be considered offensive). Sir Terry’s works on the other hand have stood the test of time magnificently, and even this early in his writing career he is standing up for fairness and respect. At one point his robot speaks disrespectfully of one of the alien races they encounter, and his is firmly put in his place:
“There’s guards all over the place, boss. I can’t find that gecky frog anywh-”
“That’s shape-hatred talk, Isaac.”
OK, yes it’s a joke about what we now call political correctness, but the point is that the protagonist rejects the idea of judging people because of their body shape. In the 70’s jokes about otherness were the staple of most comic routines, but here we have Pratchett avowing such ideas.
There’s an early incarnation of the Assassins Guild here as well – when an assassin tries to kill Dom he is asked at one point: “I hope you were given due notice” to which he replies “Oh yes, three days and a regular United Spies contract.”
There’s even a character (a planet sized being) who speaks in caps, as famously practised by Death.
If you enjoy Discworld then you might find some moments of The Dark Side of the Sun diverting. As sci-fi it’s inevitably dated and doesn’t pretend to be more than a fairly derivative piece of light entertainment. The switch to fantasy was the light-bulb moment for Pratchett and once he began the DW series he never really looked back. It’s still interesting to read this early work with its little hints of what was to come, but I recognise this won’t be for everyone.
