How far would you go for the one you loved? Madrigal Cabriole would do anything for Allegro Danseur. He isn't just her childhood friend and adoptive brother, but the man who owns her heart. Which is why, for the sake of the treaty between his Famiglia and their arch nemesis the Cavaliers, she'll swallow her pride and endure the contempt and disdain of his fellow noblemen. Better to have a bruised ego than a headless fiancé. But as the treaty's negotiations are drawn farther out, and the wedding encroaches ever closer, the further she and Allegro drift apart. Madrigal believes sinister means are afoot in the form of the Cavalier leader but cannot take action without putting Allegro's life on the line. Desperate, her fears drive her into the home of a mysterious man who promises eternal happiness, for a price she's unsure she's willing to pay. Madrigal must decide if her heart is worth the cost, because once a heart has been stolen, it can never be returned.
