Falling Free, written by Lois McMaster Bujold and published by Baen Books in 1988, was the fourth book written in the Vorkosigan Saga. Chronologically, it takes place about 200 years before the events of the main sequence of books. It is not, however, the earliest story; that is "Dreamweaver's Dilemma." It was first published by Analog as a four-part serial from December 1987 to February 1988; it has been collected in the omnibus edition Miles, Mutants and Microbes.
