I grieved with Narcissa as I read this. The language is rich and carries the reader into her reality. The warnings refer to happenings in the previous piece in the series, and should not scare you off. Rape as a weapon of war is not sexualized, and handled well. Ultimately this is a character study, with the kind of world building we could only wish was included in the source canon material.

Narcissa knows there is another woman - but when she learns who and why, she must make hard choices to bring them all through a hell of someone else's making. A journey of silent dignity and selflessness. Narcissa's perspective on The Blue Vial. (You can read this on its own, but if you're going to read both, it's better to read Blue Vial first).
