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.
