This note contains spoilers for the book.

Starts at the men's college in England, not to be confused with the women's college in France (Greenlaw) that the previous book started at. Very, very different approaches to magic, and to teaching.

Jane from the previous book is a major player in this one, but there's little other connection—except that the new Warden of the West is important. Her brother is a scholar of Glasscastle. The wizards of Glasscastle University mostly think the Wardens are an old superstition.

This one involves military research, a particularly dumb secret weapon, ambition, treacheary, all the usual things. An American sharpshooter is the main character.

The clannishness bothers me. Neither school is much aware of the knowledge or approaches of the other. There's no kind of cometition, no kind of cooperation; they pretty much ignore each other. Of course the sex line was rather harder than than it is now. But it clangs to modern ears; that's not a good enough excuse.

Jane drives her brother's very large motor car around a lot in this one.

Both of these were very clean, well-written, pleasant, despite the observed glitches.
