Oxygen

Rate this book
Valkerie Jansen is tough, beautiful, and has an uncanny knack for survival. But that doesn't explain why NASA picks her to be part of a two man, two woman crew to Mars -- or does it?

Bob Kaganovski, the ship's mechanic, is paid to be paranoid -- and he's good at it. After a teeth-rattling launch, Bob realizes that his paranoia hasn't prepared him for this trip. He can deal with a banged-up ship, but how's he going to survive the next five months with HER just a flimsy partition away?

Halfway to the Red Planet, an explosion leaves the crew with only enough oxygen for one. All evidence points to sabotage -- and Valkerie and Bob are the obvious suspects.

Oxygen is a witty, multi-award-winning roller coaster ride, with a plot that moves at the speed of light.

The authors had hoped to work in some cool controversy on science, faith, the meaning of life, the existence of God, and possibly even the Coke versus Pepsi debate, but they were having so much fun writing the story that they forgot to offend anyone.

This is the second edition of Oxygen, released in September, 2011. It includes four bonus appendices that will specially interest aspiring authors and readers who want to know the story behind the story. Learn how John and Randy sold this novel to a publisher in less than 7 weeks -- without an agent. See the exact proposal they used to sell the book. And read their hilarious critiques of each other's first scene.

Originally I first heard of this book when I was fishing for tips on how to write novels and I came across Randy Ingermanson’s Snowflake Method. Then I noticed this book and thought I’d give it a read after having seen glowing ratings and compliments about its pace and story.

Upon finishing, my personal review was not one of glowing stars and meritorious comments.
The beginning of the novel sucked. Sure, I was thrown right into the fray with our protagonist, Valkerie fighting for her life, that part was exciting and demonstrated the ingenuity and quick thinking of our main hero. Yet after she is rescued by people from NASA, she immediately turns into a juvenile who seemed more like a high school girl who fretted about how another man, Bob, thought of her instead of being the confidant, accomplished scientist she is. The other male protagonist, Bob, is just as incompetent when it comes to the other sex. Having been scarred with a previous romantic mishap, he doesn’t talk much, which is completely alright until he meets Valkerie. After which he turns into another sensitive high school boy whose head was filled with…”I wonder if she likes me” “What would I do if she doesn’t like me”
So that was the start, which I thought was uninteresting.

The book picks up pace around the second half and progresses at a great speed until the end which I won’t spoil for you. However, the author in the attempt of trying to keep up the fast pace makes some of the chapter’s ending seem forced, sometimes even deliberately strained to make it look like something big was going to happen next.
The dialogue was cheesy at times, almost to the point I wanted to stop reading and the book actually ended prematurely, at least it felt like that to me.
A redeeming factor for this book was the attention to scientific research and detail, that I can see from the book and appreciate it. Also the tension created in the mid point of the book between the four (more like three) crew members was well done and kept me turning pages.
Overall it was a fun read but nothing mind-blowing like most of the reviews out there. Would have been better if the characters acted a bit more sophisticated than clueless lovebirds searching for love; this could have been because the author’s voice was a bit too strong in places and revealed too much. I don’t really want to know if a guy thinks whether a girl likes him or not, at least not in the form of “I wonder if she likes me.” Too straightforward and poorly done.

I appreciate the author’s attempt at resolving religious issues on God and what not, but that part I mostly skipped because that just was not what I was interested in; even the romantic relationship between the two main leads were strained because of this, I thought this was slightly irrational. It just seemed too close minded in 2014.
Anyway, pick this book up if you are looking for an exciting ride(that starts slightly late) for a causal afternoon read. Don’t expect the characters to leave a lingering impression though. Probably will not pick up the sequel.

“Oxygen” by John B. Olson and Randy Ingermanson is a great new science fiction/thriller. NASA wants to send a crew of four to Mars, two men and two women. While they are on their way to the Red Planet an explosion seriously damages their ship. Now the question is, who did it? And why?

I really enjoyed this novel. Christian fiction is not genre I normally read, and although there are religious questions throughout the book, I didn’t feel like it was being crammed down my throat. The questions were basic and timeless, and hardly a turnoff, no matter what your religious views.

The character development was fantastic. They were realistic and intelligent. The readers are shown not only their attributes but also their flaws in every action and conversation. Bob is confused, hurt, and incredibly suspicious thanks to his past; the big question is whether his behavior is at all warranted. I enjoyed the conflicting viewpoints and behavior; the characters were all so human. In the end only one character decides to trust the others without any proof, only faith. A decision every person faces at one point in their lives.

This novel investigates the complexity of human relationships and morality. It also does an extraordinary job educating the readers on NASA and space travel. The questions brought up when asking whether there really is life on Mars, or anywhere other then Earth, are incredibly interesting.

For those who love science fiction that’s not just skin deep, this is a great new novel. It was thought provoking, entertaining, and full of mystery and suspense. I can’t wait to read the second of the series.


I received this book through Goodreads First Reads. This in no way influenced my review in any way. I was not compensated for, nor required to, write a review.

Ok, so I was really disappointed in this book, despite its heralded, award-winning reputation. Maybe I'm just not as big a sci-fi fan as I once was, or maybe I'm too selective in this genre, but I grew tired of it quickly and just wanted to get to the end simply to see who survived and how. My biggest complaint was too many conflicts--one after the other, after the other. I couldn't keep myself in "crisis" mode and still maintain caring for the characters. The author strove to impress on us the many and varied dangers of a long-term space mission... ok, I got that. But after several hours, I almost gave up on them altogether. I just didn't care anymore. As a Star Trek fan, I appreciated the nods to Rodenberry's world, but those attempts at levity only go so far. Spiritually, also the book caused me some concern, at least up to near the end of the book. As another reviewer pointed out, it can be refreshing to get Christian characters who are flawed just like the rest of us, but the writer seemed to think he could rationally prove some of the hardest questions of faith. People less familiar to Scripture's truth may even be challenged away from simple child-like faith by his questions. My apologies to all the fans out there, but I won't be reading the sequel.

I liked this more than I thought I would. I liked that the authors brought up questions and inconsistencies of our faith, and how we can believe even in the doubts, that God is so much bigger and so much more than we could ever imagine. Plus the adventure of going to Mars. Even though the technology has changed since it was written in 2001, I think the story holds up well.

It's like The Adventures of Tintin: Destination Moon goes to mars.

I can't really talk about this without comparing it to The Martian, by Andy Weir. Both are about near future manned mars missions (bar that, they're completely different). In general, I think The Martian was more realistic, as far as technology, methods, how NASA operated, ect. it was pretty believable. Except on one point: Mark Watney was on Ares mission 3. This book's crew was Ares 10, which seems more realistic to me, considering that we didn't get to the moon until Apollo 11. Okay, I'm done comparing it to The Martian.

I wasn't too big on how the thematic material was dispensed. It wasn't bad, but it definitely could have been better.

If you've been following me, you know I'm not prone to rave about books, but I've got to say, this book had one of the most epic endings I have ever read. I thought for sure it was going to be cheesy, but it had a twist right at the end that made me want to cackle with delight. It still does. I won't spoil it, but it was very much like the twist right at the end of Point of Impact (which is nothing like the movie, btw), and really made the whole book for me.

It was totally worth buying.

I'm not sure when I'll read the sequel.

A while ago I took advantage of a cheap Kindle download of John B. Olson and Randy Ingermanson's 2001 novel Oxygen. though I'm not a fan of its genre (near-future scientific thriller), I wanted to see if Snowflake guru Ingermanson could actually write fiction and was attracted by the "Bonus Goodies For Aspiring Authors" included in this edition.

The story is about a space mission to Mars. We meet the characters—the astronauts— when they are in training before the mission launches. The main male character, Bob is outwardly self-assured but inwardly fearful that he will be axed from the mission. The main female character, scientist, medical doctor, and resourceful woman extraordinaire Valkerie joins the crew late, bumping Josh to the consternation of some. Kennedy and Lex, the other male and female astronauts are mysterious and sometimes appear sinister—all the more because they are not point-of-view characters and we don't know their motivations. Characters are well-developed, believable and to varying degrees sympathetic.

On launch day we experience the bone-shaking liftoff through Valkerie's consciousness and the various mishaps that follow through Valkerie's and Bob's. One of the crisis points of the plot occurs when the ground crew realizes that the bruised space craft hurtling toward Mars doesn't have enough oxygen to get the crew of four safely landed on the red planet. This shortage combined with the hostile setting makes for a fascinating exploration of the psychology of people under pressure, as the astronauts together with mission control decide how to handle their dilemma.

The authors' probing of the themes of trust, loyalty, love, and faith make the story more than just a scientific thrill ride.

I enjoyed it. The authors in their back matter, explain how they did their best to make it a page-turner (John Olson: "I was obsessed with giving the reader the most extreme ride possible. I wanted the tension to be maxed out at every point in every scene of the book..." - Kindle Location 7579) and it certainly was that. In fact, I could have used a little more down-time amidst all the high angst.

The back-matter where the authors talk about selling their idea to an agent, explain how they researched and wrote the book, then quote parts of their submission (with comments of what they would do differently if they were submitting that proposal today) was enlightening. This ten-year-old award-winning book stands up well though its now-nearly-upon-us dates (launch January 2014) feel a bit spooky.

Hard science fiction isn't my usual reading, but one of the authors of Oxygen, Randy Ingermanson, developed a popular outlining method for writers (the Snowflake method) and I found out about Oxygen on his site. I'll admit that what grabbed me was the romance aspect of "science fiction romance", but I ended up thoroughly enjoying everything about this book.

The story follows a team of four, two men and two women, who are to be the first astronauts on Mars. NASA is short on funds and has had to turn the whole thing into a reality show for money, and that and other political considerations nearly trash the mission even before it starts. Two of the astronauts, Valkyrie (one of the women) and Bob find themselves attracted to each other but have difficulty working past preconceived notions and other misunderstandings between them. A lot of other figurative (and literal) baggage gets launched into space with the crew, and when things go terribly wrong, they have to struggle between their suspicions as to who is to blame for the problems and the need to trust their crewmates utterly. The excitement and suspense are non-stop, and I stayed up way too late one night to finish it.

Some reviewers have pointed out the emotional immaturity of some of the characters; I grew up with scientists (though the gene completely skipped me) and their colleagues and grad students, so I've learned first-hand that just because someone is brilliant in one aspect of their life doesn't mean they have to be brilliant in all (or any other) aspects. So I didn't have a problem with that.

This book is also often classified as Christian science fiction. The two main characters, Valkyrie and Bob, are both Christians (of different flavors, evangelical and Catholic), but the book doesn't deal specifically with Christian theology or beliefs. It does take an interesting look at the conflicts brought up by the arbitrary and false notion that science and faith cannot coexist (the scientists in my family are also religious), and also delves deep into the nature of faith when Valkyrie finds the burden of ensuring the mission's success resting entirely on her shoulders with no one else able to help. As a Christian myself, I found these questions well worth looking into, but I didn't feel like I was sitting through a Sunday School lesson, and the story always took precedence over the message.

Fun, exciting, suspenseful, with a sweet romance and some thought-provoking ideas, Oxygen is highly recommended even to readers who aren't usually into hard sf.

Oxygen is a well-researched and crafted, near future, Christian science fiction novel. Published in 2001, the story is set in 2014 during the first manned mission to Mars. Microbial ecologist Valkerie Jansen is assigned to the Ares 10 as late replacement. This alone would cause strain for the crew but her faith adds another level of tension. When a near catastrophic explosion occurs the crew of two men and two women must learn to trust each other or perish in the cold of space. While I pray that the first mission to Mars does not have problems if it does I hope they have someone as resourceful as Valkerie. I also hope they never become as paranoid as this crew becomes.

All too often Christian fiction is second-rate fiction but this is not the case with John Olson and Randall Ingermanson. This is excellent science fiction. Historical details and NASA jargon are sprinkled into the story along with technical details about the spacecraft and spaceflight. These realistic fine points make the story much more compelling.

The best fiction writers present their stories through setting, action, thoughts, and description. Many Science Fiction stories suffer from lengthy paragraphs of telling. While Oxygen does have some telling, much of the story is told through dialogue or shown through actions.

As a Christian and a lifetime reader of Science Fiction, I recommend Oxygen to fans of the genre.

Good story, chock full of disaster scenario after disaster scenario, once they got off the ground. I really liked the realism of the science aspects of it, but I found I really didn't get into the characters too much. If anything, it actually flowed TOO fast - not that I couldn't put it down, more like it seemed to jump very quickly from point to point, leaving the reader to infer a lot and glossing some details I think it would have been nice to include.

Well, this will teach me to look at the publishing house before I begin a book. What seemed promising devolved into a poorly executed sf story--too closely copied from Apollo 13's troubles as well as stealing lines from that movie and the moon landing-yuck! It's almost as if the author only knows anything about NASA and space flight by watching movies . . . hmmmm.

Oxygen(Oxygen Series,Book One)By John B. Olsen and Randy Ingermanson

I purchased the book Oxygen for two reasons one of those being to read the bit at the end with tips for Authors. I've no idea if the copy other people get will have the same. Another reason was that it looked as though it would be a good Science Fiction read. It was.

I want to thank the authors for a very good read. I read the story first knowing the part at the end could have some spoilers. Part of the stuff in the back was how they came across their idea and how they edited it and how they pitched the idea to the publisher. All of that I have learned to take with a grain of salt especially when people start using buzz wordy things such as High Concept. That they thought that this was the time to focus on the Red Planet would almost make sense except we've been focused on that since long before Edgar Rice Burroughs gave us John Carter of Mars.

This book is good science fiction and there has been at least some attempt at rising above the usual level that (pure or hard) science (fiction) settles at. What I mean by that is that in many (pure or hard)SF the science becomes the driving force of these novels (almost like the science is the protagonist) and the characters take back seat becoming cardboard entities that point and explain the science. Cardboard like that image floating to the ground in the opening of the movie Making Mr. Right. Thankfully this story is about the people.

Of course with today's sometimes bad press with the public lives of the people in the space program it's not too far fetched to see that this novel become peopled with a few quirky gems. We have everything from the paranoid to glory seeker to the super secretive. One would almost expect with all that against us we would have trouble getting things off the ground. Team work is important here and I'm not sure these people would always be considered team players.

Yet there is that element in life and so it might figure even into a good Science Fiction novel, though some might argue that in some respects the writers should shun certain attempts a making their characters too real. After all we need the heroes and the ones we can look up to, unless the idea is to write a bit of over-dramatic scripted Reality TV.

There are moments when the author's tend to go overboard with the paranoia and over-dramatic. I believe they try to keep it balanced for the most part and it's much better than trying to believe the space travelers are all going to be flesh and blood robots who always get along. It's difficult though and sometimes it looks like the human element is where things fail rather than the science when in reality a lot of drama in space has been in little things in the technology that goes awry.

The story begins with Valkerie- working too close to an active volcano- trying to get research data at the risk to her life.We switch to Bob Kaganovski working with NASA and a few friends-getting ready to man a flight to Mars. Something is going down and Bob's almost certain he's being replaced on the project. Meanwhile Valkerie is saved by Steve Perez and Roger Abrams-she later learns they are from NASA. Eventually she'll find out that she's someones replacement.

That's already a formula for competitiveness, suspicion and paranoia and its only the beginning.

For the most part the various people in the story are believable. Even most of the situations that occur through misinformation or lack of information seem plausible. One would like to think the people at these agencies are just a bit more together than that. Truth has proven that there are still glitches on the human side while trying to act out the part of near robots when things go wrong we don't often know how everyone will react.

The writing seems solid. I didn't check all the facts, but the science is believable.

One thing worth mentioning is that the authors made use of the same plot trick of another of my favorite authors. I suppose that this could be coincidental, though it would mean that neither author has read a lot of Robert Heinlein's stuff, there's a plot point that drives this story. This could be a spoiler so just be aware;

This plot point is very similar to the plot of The Man Who Sold the Moon by Robert Heinlein. After reading this book if you have not read TMWSTM; check it out and see.

It boils down to the simple economics of having a reason to travel in space. Something to help drive the funding of research and development.

Oxygen is pretty good stuff; barring the overtly B movie paranoia moments. A pleasure to read for Science Fiction and Fantasy lovers with a little for anyone who is interested in the science parts.

On a side note: This is published under a Christian label, but is not a hardline Christian story- it's more progressive- science rational. I think the religion is left for the thinking reader to work out.

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.

Kudos to the authors for good pacing and using their scientific prowess plus research to make this novel realistic that way. This is the only thing that saves this book from getting one star and I really wanted to like this book. However, it's clear that the publisher they used or the authors didn't hire a good developmental editor even though the copy editing is good. As a result it reads less professional and more self-published even though originally it was done via an independent press. There are other execution errors.

The characters and dialogue could have used the input of a good developmental editor to help them flesh things out. I also far prefer the cover to the edition I bought, Oxygen (Oxygen, #1) by John B. Olson over the MPE which to me is poorly done and misrepresents the book.

Don't use their writing method alone if you want to write well. Beginners need professional input from people who know what they are doing, not only from beta readers.

No book is really perfect, but this one was awesome.

This author is deep into research in every area. So some of the text tends to be over most people's head. Certainly over my head! But it didn't deter me from tracking with the story. About halfway through I adjusted to the style of writing and slid right into the story. I like a book that draws you in and takes you away. This did it! Other books by this author have been really great. So it was a natural choice for me. I have no regrets! And for someone who has formerly had zero interest in space travel, this book caught me Hook Line & Sinker. Way to go!

Reading it 5 years after it was set is kinda funny. The world changed a lot right after it was published, that's for sure.

It had been long enough from my last read that I'd forgotten how things resolved, so I didn't have any spoilers in my head as I was doing this re-read, which made it more enjoyable than it would have been if I'd remembered more. I guess I'll have to wait until 5-10 years before my next read, just to make sure I'm not spoiled. :-)

Astronauts

I do not consider this a sci to book. Yes, it is about a trip to Mars, but no aliens of any kind. It is suspenseful and kept you guessing, never to be right. Fantastic character development. It was great reading a book that took longer than a day to read (due to its volume).

Fast-paced, tense, and incredibly well-researched, this book doesn't give you time to take a breath. It throws your right into the thick of it and the tension doesn't let up. The characters are complicated but loveable, and the plot keeps you on the edge of your seat. One of my favorite sci-fi books of all time.

Loved it. I'm a writer of a book on Quantum Physics and a lover of SciFi and this is book is a wonderful romp that is part Apollo 13 part who-done-it and part romanic triller all rolled into one. I couldn't put it down till I read it from cover to cover... I off to load up book two! Michael-David

As a hard sci-fi fan, I really enjoyed this book. I had a hard time putting it down at night because of the suspense. Honestly though, if NASA ever selected a crew half as incompatible, it would be asking for disaster. That’s why competitive crew selection is such a bad idea.

I really enjoyed this book. It kept me hooked from page to page nonstop. It was fascinating that this is a Christian sci-fi book (which is really rare). At the same time, the religious elements were toned down and not awkward. I just started on the sequel.
