Parasite
<h2>They're closer than you think...</h2><br />A guard discovers an unusual lifeform on her remote moon outpost. She disregards protocol to investigate it, with catastrophic consequences.<br /><br />The parasitic alien wears its victims' skins and adopts their personalities. It's a perfect disguise, and allows the creature to spread without being detected. By the time humanity realises it's facing extinction, a third of its six hundred space stations have already gone dark.<br /><br />As the alien's ruthless progress collapses communication networks, wipes out defences, and leaves hundreds of stations to fend for themselves, a handful of remarkable individuals must find a way to battle the greatest threat the universe has ever encountered.
