Olson and Ingermanson blend crisply realistic astronautics with the untidiness of human emotions, creating a thriller about people who must—yet cannot—trust each other if they want to survive.
Valerie Jansen is shocked when NASA interrupt her survey of volcanic microbes to discuss her joining the astronaut program. Getting to train alongside the crew of the next Mars mission is a dream come true, until her budding friendship with Bob Kaganovski, the flight engineer for mission, is shattered by mutual distrust. With plenty of training to focus on and Bob due to launch soon, they can avoid each other; until Valerie is unexpectedly fast-tracked from astronaut candidate to replacement crew for one of the Mars mission, she and Bob must face months in a small module relying on each other for their survival—a survival that seems impossible when the module loses most of its oxygen supply.
Set in an early Twentieth Century where the “Mars or Bust” campaign of the Nineties was successful, this novel is deeply grounded in real-world astronautics; thus, while a plot about establishing a base on Mars places it in the science fiction category as well as the modern thriller, it sits at the hardest edge.
However, this is not simply a fictional veneer over descriptions of orbital mechanics and engineering challenges; the novel also features a plot build around interpersonal tensions and the probability of espionage, that only becomes more tense when the module suffers several probable acts of sabotage that would be hard for anyone other than the four-person crew to engineer.
While some scenes are from the viewpoint of various other members of the Mars Program, the majority of the book is divided between Valerie and Bob. In addition to offering the reader more perspectives on general and specific situations and challenges without the need for implausible info-dumps or dry lectures, the dramatic irony allows the reader to know that both Bob and Valerie are innocent of malice and thus to have a firmer foundation from which to riddle out what the truth might be.
Although the reader is aware of their innocence, the two of them fear the worst of each other for much of the book. As with any plot that relies on two characters repeatedly misinterpreting the other’s actions and motives, the individual reader’s belief that they should just talk to each other will vary. Thus—although Olson and Ingermanson prime the situation in their plot’s favour by both having one of the reasons Bob is so good as a flight engineer be that he never assumes the best and overt mentioning that one of the neurological symptoms of alterations in module atmosphere is paranoia—the human side of the plot might prove frustrating in places for some readers.
The engineering side of the plot is well-balanced between providing necessary context and adding detail for the sake of showing the authors have done their research. This gives each of the individual problems the module encounters both plausibility and tension. However, as with the human side, the next issue arises with little to no break; depending on reader perspective, this might strengthen the sense of both how dangerous going into space is and how likely it is there is a saboteur onboard. or start to feel like the authors are extending things by having anything that could go wrong go wrong.
With both Valerie and Bob professing Christianity, this book is not unreasonably labelled Christian fiction. However, as the authors adhere to the hardest of science to the very end of the book, it sits very much in the end of the genre that deals with reconciling the place of faith in a modern rationalist world and the power of hope over despair rather than the end that has miracles save the prayerful.
Both the truth of what caused the chain of issues and the solutions draw on both the human and engineering facets equally, creating an ending that is fully supported by the evidence and plausible human behaviour. However, depending on reader preference, ending at the moment the danger is over rather than showing some of the longer term impact of the situation might feel a touch abrupt.
Valerie and Bob are both plausible characters—given the context that they are astronauts, so must be the sort of people who are highly skilled in multiple areas. This physical and mental brilliance is also balanced by a lack of emotional perfection.
The supporting cast each display a similar blend of great competence in multiple areas relevant to their role in a manned spaceflight program combined with an entirely human tangle of conflicting drives and emotional blindspots.
Overall, I enjoyed this novel. I recommend it to readers seeking a thriller that is driven by realistic science and the effects of extreme stress.
