When you're the seventh son of a seventh son, life is an adventure and you are destined for great things. When you are the seventh daughter of a seventh son, life is perfectly ordinary and you are destined for nothing in particular.
When her oldest sister is kidnapped by a witch masquerading as a matchmaker, Rosemary will venture into the magic-filled forest to search for her. But the forest is not as simple as the fairy tales of Rosemary's childhood make it seem. There is a battle brewing, and Rosemary may have bitten off more than she can chew. With the help of a talking fox and a forest troll, she will attempt to rescue her sister and the rest of the forest from the evil that is threatening to take over, and achieve a destiny even more important than she could have imagined.
