The duchess of the House O'Brian. She has ties to the criminal underworld and manages a brothel.

It is common knowledge that nobles will do anything for power; lying, manipulation, and extortion are the usual tactics. However, one family is exempt from this generalization: House Grail, whose main tenets are truth and integrity. The youngest daughter, Constance Grail, is just as moral as the rest of her family, believing in always doing the right thing and helping those in need. 

However, these ideals do not help her when her fiancé cheats on her with another woman. Framed by his lover in the hope of her downfall, Constance has no one to hear her pleas for justice. Everyone turns a blind eye, save for one—the spirit of the infamous Scarlett Castiel—who possesses Constance and turns the tables on her accuser. However, this aid does not come without a price. 

Ten years ago, Scarlett was executed for the attempted murder of Princess Cecilia. But this was actually a setup; as blunt and harsh as Scarlett could be, she would never stoop so low as to use poison. She has no idea who orchestrated her incrimination, but Scarlett demands that Constance—as the only one who can see her—help her exact revenge on all those who wronged her!

The Grail family has a single guiding principle in their lives—Thou Shalt Be Sincere. However, sincerity alone can only get a lady so far in the twisted world of high society...as meek Constance Grail soon learns after she is framed for petty theft and loses her fiancé and reputation in a matter of minutes. But one gaze on her isn’t quite as chilling as the others, though the woman’s uncanny resemblance to Scarlett Castiel must be a coincidence. After all, Scarlett isn’t just extremely wicked…she’s also very much dead.

As a viscount’s daughter, Constance Grail is an ordinary girl whose only notable trait is sincerity, leaving her with no real options when someone steals her fiance and falsely accuses her of petty theft at a ball. While Connie awaits her undeserved punishment, a ghost appears to offer a bargain. The spirit is none other than Scarlett Castiel, a noblewoman once praised for her beauty, lineage, and undeniable charisma-and executed some ten years earlier for her wicked deeds. When Connie accepts this proposal, she is possessed by the infamous spirit who instantly turns the tide on her tormenter, thus saving the hapless girl from her miserable fate. It’s never wise striking a deal without knowing exactly what you’ve committed to, though...or you might find yourself bound to a ghost dead set on revenge against her own enemies!
