Bujold is best known for her series of novels featuring Miles Vorkosigan, a disabled interstellar spy and mercenary admiral from the planet Barrayar, set approximately 1000 years in our future. The series demonstrates Bujold's mastery of various science fiction genres and sub-genres. Earlier titles are generally firmly in the space opera tradition with no shortage of battles, conspiracies, and wild twists, while in more recent volumes Miles becomes more of a detective. In A Civil Campaign, Bujold explores yet another genre: a high-society romance with a plot that pays tribute to Georgette Heyer (as acknowledged in the dedication)
