One hundred years from now, United Nations Weapons Inspector Nathan Kane is dispatched to COLD HARBOR, a government research space station orbiting the Jovian Moon Europa. His mission is to analyze and access the origin and danger of what could possibly be the most significant discovery in history. But there is a glitch in the works - also orbiting Europa is a space platform operated by the multi-planetary super-conglomerate, DOORS. Fully automated, down to its staff of chip-in-head indentured servants, DOORS has but one motivation as it tries to wrest control over this remarkable discovery - to win the ancient prize at any cost. Now Kane and the crew of Cold Harbor find themselves in a life or death struggle, one in which human civilization could hang in the balance!
