I love Bujold, and Miles may be my very favorite of all sci-fi characters. Therefore, I'm obviously recommending this collection of three Vorkosigan stories ("Borders of Infinity," "Brothers in Arms," and "Mirror Dance.")However, at the risk of sacrelige, I do feel that the Vorkosigan series peaked just before Mark was introduced. "Mirror Dance" and a couple of others near by in the chronology - for instance, "Memory," - are not quite as enjoyable to my tastes.New readers of Bujold should certainly read the series in published (not chronological) order, starting with "The Warrior's Apprentice" and "The Vor Game," and then proceed on if they like so many of us have fallen in love with Barrayar and Miles in particular.
