No joining the army, or going into interstellar space, until you’re at least 75 years old.

Each month, the Tor.com eBook Club gives away a free sci-fi/fantasy ebook to club subscribers. We’re happy to announce that the pick for June 2017 is John Scalzi’s seminal work Old Man’s War!

Responsible for protecting humanity, the Colonial Defense Force doesn’t want young people; they want people who carry the knowledge and skills of decades of living. You’ll be taken off Earth, never to return. You’ll serve two years in combat. And if you survive, you’ll be given a homestead of your own on a hard-won planet light-years from home.

John Perry is taking that deal. He thinks he knows what to expect. But the actual fight is far, far harder than he can imagine—and what he will become is far stranger.

Please download the ebook before 11:59 PM ET on June 21st.
