Anna Witt, the daughter of a Guardian Angel and a Demon, promised herself to never work for her father, corrupting human souls. She was so naive to make such a statement. She was so naive in many ways. Haunted by whispering demons, Anna does whatever it takes to survive, even if it means embracing her dark side and earning an unwanted reputation as the school's party queen. Her life had never looked so dull. And all this time, Kayden Rowe, the son of the Prince of Lust, invariably occupies her heart and thoughts. When a lost message from the Angels is unexpectedly found, Anna finds herself traveling the world with Copano, the son of Wrath, in an attempt to gain the support of the Nephilim and give them hope for the first time. It soon becomes clear that Anna and the other Nephs who hope to win will not achieve freedom without a fight. This means that Anna and Kayden must put aside all the problems that exist between them; they must overcome painful temptation and face the main question: is it worth risking your life for the one you love?
