The Forgotten Sisters

While the story follows Miri Larendaughter's continued development across the series, the narrative is structured so that it can be understood on its own, as it introduces a distinct new setting and a fresh set of students for the protagonist to mentor.

The author developed the plot for this installment after briefly mentioning a swamp region in the first book of the series and deciding she wanted to return to that location to explore the lives of the royal cousins living there.
