Shards Of Honor

It was the wrong war, in the wrong place, at the wrong time, for the wrong reasons. And Captain Cordelia Naismith of the Betan Expeditionary Force would be forced into a separate peace with her enemy, Lord Vorkosigan.
Shards of Honor is the novel in which Lois McMaster Bujold introduced the science-fiction world to Barrayar and Aral Vorkosigan, Beta Colony and Cordelia Naismith. From this beginning the author has created a multigenerational saga spanning time as well as space.
Bujold is generally recognized as the current exemplar of the character-based science-fiction adventure story.
