But when the new girl in school, Eva, appears to be after Chelsan's head, Chelsan soon realizes that she'll never be safe. Elisha is back and she has a new team of 300-year-old assassins to do her dirty work. Their first target is Chelsan's Gramps: Vice President of Population Control, Geoffrey Turner. Chelsan must use her powers to help save the man who is responsible for killing her mother. Chelsan and her friends are yet again thrown into peril in order to save the world from Elisha's sinister plans. And Chelsan's tentative relationship with Turner is put to the test as they once again have to work together against a common enemy. Chelsan must defeat Elisha once and for all in the third installment of the bestselling series the Riser Saga."
