This is my first book by this author and I found the premise interesting and, unlike a recent reviewer, the physics lessons very much needed if you are to understand Kathleen's predicament! She must master control over the positive and negative aspects of her discovery from years of research. Her life, and Cadeyrin's depend upon it. I am not sure that the author is done with one book. When you finally reach the end of the book, you are wondering, how will the future be for her? Can she carry on functioning this way and be safe from further problems in the present and past?
I don't want to give away anything as it is a book for discovering the characters as well as the plot. But I do hope the author is going to bring us another one. I would like to follow along as Kathleen follows her dreams!
