Old Man's War By John Scalzi - Old Man's War #1

At seventy-five years old, John Perry is looking for a fresh start – in the army. But the universe is a dangerous place in John Scalzi's Old Man's War . . .

'Gripping and surpassingly original' – Cory Doctorow, author of Walkaway

Earth's military machine can transform elderly recruits, restoring their lost youth. But in return, its Colonial Defence Force demands two years of hazardous service in space. This is how Perry finds himself in a new body, crafted from his original DNA. A genetically enhanced and upgraded new body, ready for battle.

But upgrades alone won't keep Perry safe. He'll be fighting for his life on the front line as he defends humanity's colonies from hostile aliens. He'll pay the price for his choices. And he'll discover the universe is even more dangerous than he imagined . . .

'A space war story with fast action, vivid characters, moral complexity, and cool speculative physics' – Ken MacLeod, author of Beyond the Light Horizon

Old Man's War is the first in the series. The gripping space war continues with The Ghost Brigades.
