The elements speak to Callie, and that's only the beginning. Everything she has ever known was a twisted fabrication to protect her. Now the truth is set free. Callie and her sister are more powerful than any Faerie ever born. Now they have to use their powers to save their mother and family from the evil hands of fate that threaten to tear them apart. Welcome to her elemental reality.
