The Human Division by John Scalzi
The Human Division by John Scalzi is the fifth book in the Old Man’s War series. It’s a string of 15 short stories—some more loosely connected than others—that intermittently follow Harry Wilson—a character whom we’ve not seen since The Ghost Brigades—and these stories collectively tell the tale of humanity’s struggle to preserve its unity amidst an intergalactic conflict between Earth, the Colonial Union, and the Conclave.
