Amy has just found out that she isn't really a Cahill, but a Vesper. The branches of the Cahill family are now uniting to stop the Vespers, a rival family of the Cahills. When Amy is asked to join the Vespers, will she leave the Cahill family and take her rightful place as one of the head Vespers or will she stay with the Cahills and fight the Vespers off?
