In Book I of the trilogy, Tamras arrives in Merin's house to begin her apprenticeship as a warrior, but her small stature causes many, including Tamras herself, to doubt that she will ever become a competent swordswoman. To make matters worse, the Lady Merin assigns her the position of companion, little more than a personal servant, to a woman who came to Merin's house, seemingly out of nowhere, the previous winter, and this stranger wants nothing to do with Tamras.

When she was a child, the author of When Women Were Warriors happily identified with all the male heroes she read about in stories that began, "Once upon a time, a young man went out to seek his fortune." But she would have been delighted to discover even one story like that with a female protagonist. Since she never did find the story she was looking for all those years ago, she decided to write it.
