Man's Second Age in space. Agent 1 and Agent 2 have very little in common. Other than the facts that they're both doctors and they work for the same agency within the Intergalactic Department of Health, they're as different as night and day. She likes antiques. He likes all things modern. She enjoys reading. He prefers movies. She likes fish and vegetables. He likes animals that eat fish and vegetables. Yet, for all their differences, they, and 36 other men and women in a small agency that's part of the Intergalactic Department of Health, roam the mapped regions of humankind's territories in search of registered donors. Agent 1 and Agent 2 are partners. And they work for the L.O.C. This is their story.
