The Goddess Test centers around on girl named Kate Winters. She meets a man named Henry who claims he can heal her mom (who has cancer) if she passes the goddess test. This is an incredible book that's based on Greek mythology and definitely keeps you guessing the entire time! It's the first book in the Goddess Test trilogy which I thoroughly enjoyed!
