It's Sergeant Henry Morgan has now spent more time as a starship than he spent dead. His mission is more than a century old, but in some ways, he feels like it's just begun. A desperate distress call from Earth has brought him back to his old cosmic stomping grounds, for your standard save-humanity-from-extinction-by-alien-constructs operation. But Henry needs to realize while his species might be the new kid on the galactic block, it is not without its secrets. Many of them deep and dark, with implications that reach back to the time when he himself walked the Earth on two legs. In some ways, humanity has become more alien than the extraterrestrials. And if Henry can't figure out what this means - fast - he's going to have serious problems keeping himself and his crew safe.
