The Argeneau World . . . there are immortal people living among the mortal population today. They are descendents of an ancient civilization that was advanced technologically to the point that they began to work with bio-engineered nanos as a medical aid to fight disease as well as repair injuries from inside the body without the need for invasive surgery. These nanos used blood to make repairs and fuel themselves which meant the host needed more blood than a body could supply to support the nanos. In that civilization this was dealt with through transfusions. However, when a series of natural disasters (earthquakes and volcanoes) brought an end to that civilization, only those people the nanos had been tested on survived, and they suddenly found themselves in a primitive society. Without their much needed blood transfusions, many died, but in others the nanos lived up to their programming to keep the host at their peak condition and forced a sort of evolution on them, bringing on fangs, extra strength, night vision and other skills so that their hosts could get the blood they needed and remain at their peak.
That's the background, but these stories are based mostly around one particular family of immortals, the Argeneaus. However, the Argeneaus are really your typical family. I think everyone would recognize at least one member of their own family among this group. My stories tell how each member finds his life mate despite all the good intentioned interference and harassment of their loving family.
