The star of the collection is the novella "Glass Cannon", which takes up about two-fifths of the book and single-handedly lifted my rating for the whole. The rest of the contents are not bad, but a lot of them are slight: there are a few that I would call proper stories, and a lot of brief vignettes and scenes that are interesting if you're already familiar with the characters but don't stand on their own. Still worth reading for a fan of the series; and for a fan of the series, the author's afterwords talking about his inspirations and influences are also good value.
