Aine is 16 years old. She found out she's a faerie. A banshee. She has to deal with that information and go to Ireland to figure out what she wants to do. When her mother disappears she finds out her mother is the Queen of All Faeries and she is a princess. All Aine wants to do is find her mother and pass tenth grade. But a dark faerie named Grianne has other plans for her.
