Just finished a re-read of the first of Nathan Lowell's Solar Clipper series,
Quarter Share. Frankly, I just wanted a comfortable old slipper, and this series is certainly that. I'm going to read the next, at least, which is
Half Share. These are "coming of age" stories, or Trader stories, or Science Fiction, or all of the above. IAC, they're good reading, and the antithesis of MilSF. Sort of a YA SF Cozy.
