Walk the Plank by John Scalzi

The second episode of The Human Division, John Scalzi's new thirteen-episode novel in the world of his bestselling Old Man's War. Beginning on January 15, 2013, a new episode of The Human Division will appear in e-book form every Tuesday.
Wildcat colonies are illegal, unauthorized and secret-so when an injured stranger shows up at the wildcat colony New Seattle, the colony leaders are understandably suspicious of who he is and what he represents. His story of how he's come to their colony is shocking, surprising, and might have bigger consequences than anyone could have expected.
