Lois McMaster Bujold (born November 2, 1949) is an American author of science fiction and fantasy works.
Bujold is best known for her series of novels featuring Miles Vorkosigan, a severely-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 a detective. In A Civil Campaign, Bujold explores yet another genre: a high-society romance story with a plot centered on a catastrophic dinner party, with misunderstandings and dialogue justifying the subtitle A Comedy of Biology and Manners. Her psychological insights and creation of complex characters are particularly appreciated by many readers.
Bujold is a highly successful writer, having won the prestigious Hugo Award for best novel 4 times, a record matched only by Robert Heinlein. She has also won the Nebula award for best novel, and her novella The Curse Of Chalion won the Mythopoeic Award for Adult Literature and was nominated for the 2002 World Fantasy Award for best novel.
Bujold currently lives in Minnesota. She is divorced and has two children.
