Reader review for Adrenaline
Since book too new for editorial reviews.

Reviewer: Harriet Klausner from Morrow, Ga. US
“Fans will feel they are on ADRENALINE with this action-packed medical research thriller that never slows down until the bridge forms a final surprising coupling. The story line is at its best when it concentrates on James, Darcy and his sister. Jenny is a role model as never stopped believing that God will take care of her in some fashion. When the plot switches to the Invisible Man, it loses a bit of its momentum though he is the key to much of the adversarial moments. John B. Olson deftly provides sub-genre fans with a fabulous terse tale that will excite readers who will search for his co-authored Martian works.”

Editorial Reviews for Oxygen

From Library Journal
In 2014, microbial ecologist and medical doctor Valkerie Jansen is thrilled to be part of Ares 10, the first manned mission to Mars. Unfortunately, the other three crew members resent her because another crew member was cut to make room for her and because she’s outspoken about her Christianity. From the start, problems plague the mission, and because of high winds at the launch, a tail fin clips the tower, leaving the rocket damaged. As Valkerie begins to believe that the commander is sabotaging the ship, her fellow crew members suspect that she’s developing a paranoia complex. When a bomb destroys part of their power supply, everyone points the finger at someone else. With their oxygen running out before they can reach base camp on Mars, a radical suggestion threatens the crew’s stability even further, and Valkerie must rely on her faith to help her survive. Olson and Christy Award-winning Ingermanson (Transgression) combine solid sf with an increasingly tense mystery for a fantastic addition to any collection.

From Booklist
*Starred Review* Only a few years ago, science fiction seemed a vexed genre in Christian fiction, but Olson and Ingermanson demonstrate how far it has come in Oxygen, the meticulously authentic tale of a mission to Mars that goes awry. Pressured by the media to launch during prime time and fearful that anything less than a dramatically successful mission will cause congressional funding to evaporate, NASA cuts some corners and imperils the mission’s power supply. Valkerie Jansen, the Christian physician assigned to the craft, and Bob Kaganovski, physicist and space mechanic, join two others in righting the handicapped craft, but in deep space, there’s an explosion, reducing the ship’s oxygen supply. To conserve it, three crew members are placed in comas, while Valkerie guides the ship onward, conserving power and oxygen in a scenario reminiscent of the flight of Apollo 13. Olson and Ingermanson draw their characters carefully, keep tension high, and introduce real spiritual dilemmas without being preachy. They capture the ironic repartee of astronauts to the last nuance. The result is a real delight. John Mort

“From the vivid first danger...to the unexpected conclusion, this tale will keep you turning pages late into the night.”

“Olson and Ingermanson combine solid science fiction with an increasingly tense mystery for a fantastic addition to any collection.”

Editorial Reviews for Fifth Man

From Booklist
Olson and Ingermanson’s Fifth Man is a sequel to their brilliant Oxygen. The same crew, more or less marooned on Mars, returns, but not much happens by way of Mars exploration except for the discovery of ice. The crew’s frantic journey to capture enough ice to manufacture escape fuel makes for some fine scenes, but the authors pump up suspense with the gimmick of a “fifth man” who might be a stowaway, an alien, or a figment. A convoluted sabotage plot back at NASA grows rather tiresome, too. Even so, this is a skilled writing team, and they've done their research. The sequel doesn't equal the original, but it’s good stuff. John Mort
