Excellent Series
Read it fast and don't try to justify the "science" in this fiction, because it is as much magic as anything I've read. It vaguely reminds me of old Andre Norton books. Hmmm. She turned out to be a Grand Master of Science Fiction/Fantasy.....
Who was it that said science appeared as magic when the science was sufficiently advanced.
Stairs that move; doors that open and close as people approach and depart; hand held communicators and wrist watch telephones. We take all of these things for granted now, but 50 to 80 years in the past they were all science fiction.
Captain, take us into the future.
