When a disgruntled astronaut decides to get revenge, all hell breaks loose!

By the time the final flight of the Russian space capsule, Soyuz, docks at the International Space Station, Derek Johnson—one of its passengers and the oldest astronaut to fly in space—is sick with a severe case of food poisoning that does not respond to antibiotics, and he soon dies.

Recruited to assist NASA’s medical team, Dr. Bob Kramer, a forensic toxicologist and expert witness, concludes that the cause of Johnson’s death is a mutated form of Campylobacter jejuni bacteria that is not normally found in nature.

In Soyuz—a captivating, page-turning, science fiction thriller—space exploration, mental illness, and forensic toxicology collide at the intersection of good and evil as Kramer unravels the source of a mysterious incident and suspicious deaths aboard the International Space Station.
