Billie Gwynn discovers a three-thousand-year-old family secret: they are part-Fairy, and Billie is to become the next Guardian of the portal into the parallel realm. She and her two friends, Holly and Vivian, cross over into the world of Fairy and discover its beauty.

After that, Billie must pass an initiation quest on her own in order to become Guardian. During her quest, she sees strange creatures and meets new friends, including a wise woman who gives her a magic knife and teaches her how to move objects with it. Billie also learns she has the ability to astral travel. She meets a Druid in an area she had dreamed about before she even knew Fairy existed. They surmise that someone must have called her to Fairy from her dreams. Now, Billie wants not only to finish her quest, but also to find out who had called her to Fairy and why.

After rescuing a troll named Pavlik, Billie and the little guy develop an unlikely friendship and end up going on another rescue mission. Pressed for time, they come across some danger.

While Billie and Pavlik are crossing into Troll, her friends at home are worried about her and decide to cross into Fairy to find her. During their trip, young Holly falls in love with a Fairy boy named Nick. Also, one of the Fairy Priestess teachers hears her singing and wants her as a student. Meanwhile, Vivian discovers the Lady of the Lake is her aunt and wants Vivian to be her successor.
