When paranormal abilities and a sensitive tail begin to emerge, they pose a serious problem to her pursuit of her musician love interest, Dimitrius, and her privacy. Having Huldra blood has its advantages. Enhanced hearing does wonders for her violin practice, opening doors she didn't know existed. Though Huldras are gentle by nature, she learns that if provoked, they are a sinister danger. She fears hurting the one she loves.

Alora will do the unthinkable to a priceless masterpiece in order to break the curse—risking life, freedom, and reputation—while mustering the courage to share her secret with Dimitrius, bringing romance to a long-held friendship.
