How to Tame a Monster Duke

In this noble world a duke may be kept at court only as long as his fits can be managed, and Lucian Montclair, called the Monster Duke, has none of them under control. His rages come without warning, so the marriage arranged for him is treated as a sentence for the bride. That bride is Amelia Vernon, who agrees to it for her own reasons. Her mother was murdered and her family's perfume house taken from her, and Amelia is a master perfumer herself, which she keeps hidden. She works out which scents settle Lucian when a fit begins, and she blends them for him alone. From that she gets a bargain: she calms him, he protects her. The arrangement holds, and the man everyone in the capital is afraid of becomes the thing she uses against the relatives who took the house from her. She goes after them one at a time and starts taking the business back. What she does not know at first is that the person who arranged her mother's death also holds an old formula that works on whatever it is inside Lucian that makes him rage, which means the weapon she has been building can be turned around and pointed at her.
