Callisto Run. The Vigilante's Code, #6

Some investigations don't go according to plan. Private investigator Lauren Kutyna boards the Callisto Express to identify a corporate saboteur. The job should be straightforward-observe, gather evidence, report back. Then Detective Asher J. Hunter steps onto the same ship. The man who chose procedure over her word is the last person Lauren needs watching her work. But when minor malfunctions turn deadly and the ship veers off course, she realizes the saboteur's endgame is far more dangerous than corporate espionage.
Trapped with three hundred passengers between Jupiter's moons, Lauren must decide: work alone and risk everything, or trust the detective who proved the system always comes first. Experience the tension. Start reading now.
