Seventeen characters occur in each of the three BALLARD e-novellas.
But the “incarnation” of each character in each book is different from the book before. For example, the character Ballard is a private detective in his 30’s in BALLARD motor court, a 50-something guy who doubles as the town auto mechanic and projectionist in BALLARD the republic of dogs, and a female painter in her 20’s in BALLARD bonus expeditionary force.
Each incarnation of a character in the three stories is really the same “soul.” They just represent different aspects of that soul, or different possible incarnations of that soul. I don’t mean this in a classic transmigratory sense, as in, these different “versions” of the characters are literally reincarnations of the same essential soul. It’s more like … when I think of Ballard as a character, I think of lots of things that that person could be, lots of jobs s/he could hold, lots of people s/he could fall in love with. But each of those possible versions is still … Ballard.
