"Members of the ancient House Rosebourne have a strange, intoxicating gift: the ability to infuse fragrance with magic. But when the family patriarch and last of the Rosebournes is murdered, royal spymaster Hugh Thornton has a crisis on his hands. The fate of the kingdom rests on the magical perfume William Rosebourne had promised to blend before his death. Time is running out to find the one living soul who can create what Hugh needs: Rosebournes bastard granddaughter, who is the secret heir to a fraught legacy. And she does not want to be found. Viola Lockhart is living on the edge of society, selling her perfumes at the Midnight Market, an illegal trade in fairy artifacts. When shes swept up in a raid and imprisoned, it seems even her sharp wits and unusual talents wont save her. Until she is offered salvation by the very man who arrested her and upended her world.

Enigmatic, silver-eyed Hugh offers a deal: her freedom in exchange for the legendary perfume, Immortal Rose. But Viola wants more--the inheritance that was stolen from her and her beloved mother. As they form an uneasy alliance, deadly violence stalks Viola. Someone is willing to stop the creation of Immortal Rose at any cost. And Hugh finds himself unable to guard his heart against the indomitable young woman hes invited into Foxcourt House, his ancestral home. An attraction takes hold that will not be denied. Hugh and Viola will find their souls stripped bare as they uncover the terrible truth woven into the very fabric of their kingdom. With undying love and redemption on the line, Viola faces what must never be forgotten: every bargain comes at a cost"-- Provided by publisher.
