For some reason or another, I seem to have the complete Diadem series written by Jo Clayton. I obviously followed them from the first volume, published in 1977 to the last, published in 1986. Obviously i must have liked them. Actually I don't mind a bit of space opera, though I haven't read any books in that category for years.
So for your viewing pleasure here is the complete Diadem series, all nine volumes of them.
