The Ghost Brigades are the Special Forces of the Colonial Defense Forces, elite troops created from the DNA of the dead and turned into the perfect soldiers for the CDF's toughest operations. They’re young, they’re fast and strong, and they’re totally without normal human qualms.
The universe is a dangerous place for humanity—and it's about to become far more dangerous. Three races that humans have clashed with before have allied to halt our expansion into space.

John Perry did two things on his 75th birthday. First he visited his wife’s grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce—and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding. Earth itself is a backwater. The bulk of humanity’s resources are in the hands of the Colonial Defense Force.
