Undoing the Swan Girl. Nights at the Swan

Princess and her six brothers once lived in a land cloaked by a spell of innocence. Their lives changed dramatically when their father took a new bride with malicious intent. Valentina, an herbalist witch, and proprietress of the Swan Club, a club that caters to royalty, dignitaries, and the social elite, has placed the brothers under a spell of hemlock and enslaved them at the club. Princess must rely for help on the alluring and mysterious huntsman Erich, himself a victim of Valentina.
She must infiltrate the Swan Club and gain Valentina's trust to rescue her brothers. Her adventure will come at a high price, including the loss of her innocence. But with this loss comes the possibility of love, and a new freedom which causes her to question whether the life she once treasured was actually her bondage.
