This is the first book in the Wildwood duet. This story is a version of the Twelve Dancing Princesses story with an added twist of The Frog Prince, and a setting of Transylvania with the addition of vampire-like creatures. Jena is the second oldest and has helped her father run his merchant business for several years. When his illness sends him away to warmer climates, he has her in charge, asking his neighboring brother to help out as needed. While the girls miss their father, they have a secret of visiting the Faerie kingdom each full moon to dance with the inhabitants through the night. Things begin to get more grim as winter approaches and her cousin Cezar begins to push his way to power. Jena is also worrying about her sisters attachment to a new fellow in the Faerie kingdom, who is part of the Night People. She is always guided by her frog, and Jena is the only one who can hear and understand him. Jena is placed in a perilous position of losing her family home and independence and possibly her sisters life as a death of a member of the Faerie leads to a death in the village and Cezar intent on destroying the Faerie kingdom and taking control. Jena must learn to trust her dear friends to find a way out of this difficult situation.
