The Serrano Legacy, also known as Familias Regnant, is a series of military science fiction[1] / space opera[2] books by Elizabeth Moon.
The series includes seven books total (a trilogy and two spin-off duologies), published from 1993 to 2000, and portrays a society in the distant future where the Familias Regnant serves as the governing body for an area of the galaxy.
[2] Mann favorably compares the feel of the series to older pulp fiction while noting she covers more serious topics as well.
[4] Of the series in full, Jo Walton says the books "do a lot of things right", praising the adventures, the military aspects, and the background.
[9] In a positive review of the first omnibus, Liz Bourke found the varied depiction of older women "downright refreshing".
