En Masse

Captain Neal Bishop hasn't been having very good luck. While recovering from injuries, he had the misfortune of catching his Commander spending quality time with a superior's wife. That landed him a rather dull rehab assignment body-guarding a group of scientists at an archeological site. But this site wasn't like any other. This moon had never been colonized by humans, and until a miner's drill pierced one wall just three weeks ago, this cavern had never been exposed to air.
So how did five human skeletons come to be inside? And why did one of them match Neal's DNA?When the miners start dying, and the skeletons start regenerating, Neal is convinced his bad luck isn't over yet. Sentient life is about to be redefined.
