Oxygen, a novel by Randall Ingermanson and John Olson

I recently read this book and I liked it a lot. It's near-future science fiction novel concerning a manned American mission to Mars in the year 2014. A four person crew is aboard: two men and two women. The main person, Valerie (nicknamed Valkyrie because that's cool in a geeky kind of way) is a biologist who is recently added to the team going to Mars. She feels anxiety over whether she is accepted by the rest of the crew and how they view her Chrsitian faith. One man, Bob, the ship engineer, is particularly hostile to her faith. However, she feels attracted to him as well. While on route to Mars, an explosion aboard the space craft cripples their oxygen supply. They discover that the remaining oxygen supply is only sufficient to support one of them. They must find a way to survive millions of miles from earth, and find which one of their own number is the possible saborteur. This is a gripping story with an innovative concept. The novel is written for the Christian market, but this is a novel that I'm not ashamed to admit having read. I've never been a huge science fiction reader, but this novel is so suspenseful and gripping in its interplay of human relationships and agendas that you don't have to be into sci-fi to enjoy it. The science is meticulously researched, and is presented in a readable form that you don't have to be a geek to understand it. Of course, being a geek myself, I can appreciate the fact that is it written by two PHDs. Christian faith is written into the conflicts in a believable manner, but it is not overbearing and doesn't try to convert the reader. All in all, I highly recommend this novel.
