Reading this, the conclusion I come to is that either I never actually read it – which is sad because I do have a copy – or I managed to completely forget the plot. The books tend to jump back and forth between the civilized Inner Lands and the more wild regions; this is a return to an Inner Land-focused plot. The author also likes to shift between sub-genres from volume to volume; this would be a caper novel.
This picks up a thread mentioned in passing in the first book; Janus, one of the few male Steersmen, has resigned from the order and because he will not say why, has been placed under the Ban. Until he explains himself, no Steerswoman will answer his questions.
Having survived the events of the first book, Rowan continues to follow up on the mystery of the gems, fragments of what she now knows to be a fallen Guidestar, one of the four mysterious objects in geostationary orbit above the surface of her world. Where the first book took her around the comparatively civilized Inner Lands, this time she decides to journey to the location where the main body of the Guidestar fell, a location on the far side of the Outskirts, the homeland of her barbarian companion Bel.

In “the Before Times”, book distribution in Ontario was pretty patchy and while I remember that word of mouth on rec.arts.sf-lovers was very positive about The Steerswoman, I didn’t manage to find a copy of it for my own until 1993, four years after it was published. I can tell this because when I look at the back of my copy it has a sticker from A Second Look Books dated 1993. Which I guess means the author didn’t make any money off me so let’s move quickly on to the next paragraph.
These books are what SF should aspire to be; it is a shame they are not more widely known.
