"Delf has a big hole in her life, and where there are holes there are questions. But of all the questions, one question dominates: why? Why was her family killed?
But self-pity is not a trait that her responsibilities permit. Her father needs her, and an Empire needs running. She must step into her dead mother’s dress.
As she slowly gets to grips with the vast problem before her, she finds inspiration from the past: her mother’s words. It seems she is only the latest to find herself trying to keep the threads of the Empire from unravelling, but her father is nothing if not stubborn. She must find a way past his stagnant views, and in the end, there is only one route. She must go against the Emperor’s wishes.
But as her confidence grows with insight, the truth that has eluded her for so long starts to take form. Its shape is chilling. Can she really push on and answer the question that has plagued her life? The answer will change things, and not just for her. An Empire is at stake."
I can provide a full synopsis to anyone who is interested in more detail.
