Ha, a new Vorkosigan novella - entirely in Ekaterin's PoV, set concurrently with "Captain Vorpatril's Alliance", i.e. before Miles inherits the Countship.
When Ekaterin and Enrique set out to test their new radiation bugs in the fallout zone of Vorkosigan Vashnoi, they stumble across a long-lost secret.
Take "Mountains of Mourning", a new use for the butter bugs, the establishment (and surveillance) of a fallout zone, Ekaterin and Enrique confronting the Vorkosigan backcountry... stir... and sit back. Distilled from this mixture is a tragic story, again a conflict between past and future and quite a lot of introspection into the question of how long past events remain in our memory, but unfortunately it doesn't carry the impact of earlier novellas. Maybe because Ekaterin is an outsider and therefore more of a commentator than actual participant, maybe even because the story isn't actually over at the end. It's barely begun.
In short, while it's good to revisit beloved characters, I'm not sure whether this story actually needed to be told... retold in a way...
