10 years later… Dhillon’s covert network has spread uncontrolled, reaching its tendrils of influence deep into the heart of the Transport Union. From Medina, Dhillon secretly re-routes cargo, alters transponder and IFF codes, manipulates transit permissions, recruits assets, and arranges tragic accidents for anyone who asks too many questions. As his shadow fleet prepares for their ultimate goal, Dhillon has just one more obstacle ahead of him: the crew of the aging Martian gunship Rocinante.
