"Technological virtuosity meets human vulnerability in a brutal post-apocalyptic page-turner set on Mars." - Katri Skala, author of 'A Perfect Mother'

"Reminiscent of Philip K. Dick and Isaac Asimov" - Amazon Five Star Review


It has been more than 100 years since the fall of the Martian Colonies, but Jude is a survivor. She is one of 'The Clan', a dwindling band that scratches a living from the rubble and she has a plan to give her people a future. Nothing, though, is simple in the time after The Fall. To succeed, Jude must defy friends as well as enemies on a journey into the savage, ghost-infested ruins of the ancient capital of Mars. On the way, she must truly decide who she is, and what it is she stands for. Will she go beyond even death to free herself, and those around her, of the burden of their over mighty past?

Sometimes books fall through the cracks. What can I say? I received a copy of Interchange in exchange for a review. Did it maybe take me a year to read it? Welcome to asking Kara to read things in a timely fashion. Sorry, Garrick Fincham. I’m glad I did finally dust this file off where it was lurking on my Kindle. It’s Mad Max meet The Expanse.

Jude Harrison once led the Clan, a ragtag band of Martian settlers now roaming the planet following the destruction of their home in a brief and brutal war with Earth’s navy. Ousted by her sister, Jude makes a living on the fringes of this fringe. Now she has uncovered an artifact that everyone wants: Earth, the surviving Martians, and even the ghosts of scientists past. She has no choice but to go on the run, but the question becomes, is she running from something or towards it?

Fincham described this book as “dystopian SF with Gothic undertones,” and at first I wasn’t sure about that latter label, but by the end of the book I understood. Interchange combines several recognizable tropes, leaning heavily on an atmosphere of suspense and dread. It is replete with ghosts, both metaphorical and literal, thanks to upload technology. The way this technology works implies a large helping of existential horror. Fincham examines this in some small way through the aforementioned ghosts; however, I wish the book had spent more time, especially when upload to the Interchange and interaction with its long-lived denizens becomes a key plot point for an important character. There is a lot of deep theory of mind stuff that the book hints at but doesn’t explore as fully as I would have liked.

Now, I can probably forgive it for that, as the book is rather busy doing many other things. Though not quite space opera, Interchange takes place at the intersection of political machinations by several parties: a power-hungry general, an overconfident data-analyst-turned-spy, a desperate dictator, and a scheming-yet-stymied scientist. Jude finds herself playing pawn to each of these people at one point or another, and indeed, the main conflict of this book might be summed up not so much as fighting for survival but rather fighting for self-determination.

In that way, I am ambivalent about the ending. On one hand, without going into more details, Jude succeeds in the goal of self-determination. The subtitle of this book is “A Dead Mars Novel,” implying that there could be more stories in the works—and I can see how this setting, and these characters, are ripe for that. On the other hand, the machinations of one character also come into fruition in an interesting way—it’s almost but not quite a subplot; it’s an SF Big Idea Fincham has piggy-backed onto the end of the novel in a showman-like twist that is fine but not quite satisfying, if you know what I mean. It’s very Adrian Tchaikovsky and Alastair Reynolds, which I mean as a compliment but also in the loving frustration I seem to have to reserve only for British SF authors.

Anyway, thematic satisfaction aside, I admit that I had trouble putting Interchange down. Fincham is skilled at the scene-and-sequel format of storytelling. Plenty of action scenes—the book starts with one—lead into a shorter sequel scene of recovery and recapitulation before we going on to the next problem. Jude and Santiago, the two main viewpoint characters, are adequately fleshed out. The supporting cast personalities are clearly established and telegraphed; however, I didn’t end up developing as much sympathy for them as I did for our two main characters, which I found interesting. Like, I care about Jude, but Sam and Esther? Not so much. I wonder if this is an artifact of that dystopian/Gothic mood wherein most of the characters, having been pushed to extremes in this difficult environment, are heightened people, all sharp edges, and therefore more difficult to like.

Interchange, like its title implies, is a meeting of many tropes. From colony spaceships to Mars colonies to uploaded consciousness and everywhere in between, this is a novel steeped in the best that science fiction has to offer. In the hands of some writers, such a cornucopia becomes a liability, jeopardizing unity of plot. Fincham pulls it off and crafts a story of desperation, shifting loyalty, and last-ditch plans to save the world. I recommend.

Loved this. Strong female lead - and v. believable. Written by a male author too. I often steer clear of 'hard' SF, often seems a bit mechanistic, but this is beautifully written, and not only are the characters really well drawn, but Mars itself is also a wonderful presence throughout.

The whole thing is evocative, human, sad, triumphant, and at times that kind of 'uncomfortable scary' that just gets to you. I honestly don't see why anyone who likes SF wouldn't read this. It's a cliche, I know, but I almost literally couldn't put it down.

Adventure and survival on Mars

Civilisation and society on Mars has completely collapsed leaving only the Clan, tough survivors who scavenge for parts in order to live. After a fairly slow start the pace picked up and I was interested to see how all the power struggles in this novel played out. Although science fiction it reads as more of a thriller I would say. My only criticism is the amount of typos in my Kindle version , some sentences really didn't make much sense. All in all though an enjoyable read from a new to me author.

A fantastically inventive, highly detailed, thought out piece of sci-fi, a world that coalesces into shape quickly as you read, populated by characters who feel real, and driven by a narrative that twists and turns, offering up surprises until the very end. Belter of a read.
