The Twelve Dancing Princesses (Scholastic Junior Classics)

Twelve princesses are trapped in a spell that only love can break.

Princess Jessamine loves to dance. Every night, when the rest of the castle has gone to bed, she and her sisters descend a hidden staircase to an enchanted kingdom where they dance through the night--and right through their shoes!
Their father, the king, is determined to discover where the princesses sneak off to each night. He promises that whoever can reveal the princesses' secret may ask one of them to be his wife!
Suitors flock from far and wide. Can Jessamine and her sisters guard their secret...and their hearts?
