After a disagreement on a contract, Kim is forced to go on the run where she discovers a conspiracy involving her former boss and the virtual utopia of the Luna Colonies.
Along the way she discovers an even more disturbing secret, one that extends back to the start of the Invasion and could mean the death of everyone on the planet.
