The evil magician who banished Gwyneth from her own world is trying to take the whole of her land and corrupt it to his own malevolent image. Samantha discovers with the help of her new friend, that she has a great magical ability herself, and Gwyneth presents her with a beautiful Pendant, which helps focus her magical abilities.

When she goes to this new land by travelling through a “fairy ring” in her garden, she finds herself at the centre of a struggle to gain control of this other world. She has Timmy her childhood friend, who has been promoted to a Knight, and Gwyneth to help her.
