Bujold is the daughter of Robert Charles McMaster and attributes her early interest in science fiction, as well as certain aspects of the Vorkosigan Saga, to his influence. He was editor of the monumental Nondestructive Testing Handbook generally referred to as McMaster on Materials and is memorialized here.

Bujold writes that her experience growing up with a world famous father is reflected in the same experience that her characters (Miles, Fiametta) have of growing up in the shadow of a "Great Man." She wonders why the insecurity complex and syndrome is known as "Son of the Great Man" instead of "Daughter of the Great Man."

Her brother, like her father, is also an engineer. Her brother helped provide technical details to support her writing of Falling Free.

Bujold currently lives in Minnesota. She is divorced and has two children.

Lois Bujold wrote three books (Shards of Honor, The Warrior's Apprentice and Ethan of Athos) before The Warrior's Apprentice was accepted after four rejections. The Warrior's Apprentice was the first book purchased, despite the fact it was not the first Vorkosigan book written, nor would it be the first one to be published. On the strength of The Warrior's Apprentice, Baen Books agreed to a three-book deal to include the two bracketing novels. Thus began her career in science fiction.

Bujold is best known for her Vorkosigan saga, a series of novels featuring Miles Vorkosigan, a physically-impaired interstellar spy and mercenary admiral from the planet Barrayar, set approximately 1000 years in the future. 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 Regency romance novelist Georgette Heyer (as acknowledged in the dedication). It centers on a catastrophic dinner party, with misunderstandings and dialogue justifying the subtitle "A Comedy of Biology and Manners".

The author has stated that the series structure is modeled after the Horatio Hornblower books, documenting the life of a single person. In themes and echoes, they also reflect Dorothy L. Sayers' mystery character Lord Peter Wimsey. Bujold has also said that part of the challenge of writing a series is that many readers will encounter the stories in "utterly random order", so she must provide sufficient background in each of them without being excessively repetitious. Most recent printings of her Vorkosigan tales do include an appendix at the end summarizing the internal chronology of the series.

Bujold also wanted to break into the fantasy genre, but met with early setbacks. Her first foray into fantasy was The Spirit Ring. She wrote the book "on spec", shopped it around, and found low offers, sending her back to Baen Books, where Jim Baen bought it for a fair price in exchange for the promise of more Vorkosigan books. Bujold called this experience, combined with the mediocre sales and lack of critical acclaim of that book, very educational.

She would not attempt to break into the fantasy market again for almost another decade, with The Curse of Chalion. This book was also written on spec and offered up to a book auction. This time, she met with considerable critical and commercial success by tapping into a crossover market of fantasy and romance genre fans. The fantasy world of Chalion was first conceived as a result of a University of Minnesota course she was taking about Medieval Spain in her spare time.

The next fantasy world she created was the tetralogy set in the universe of The Sharing Knife borrowing inspiration for its landscapes from ones she grew up with in central Ohio. She writes that her first readers who helped proof-read it said she got it exactly right and they could recognize Ohio features in the descriptions and dialects. She states that the dialect of the "farmers" is one she grew up around.
