Aria McCall is 19 years old and Scott McCall's older sister. 3 years ago, Aria had to leave home without any explanation and she has now returned to Beacon Hills to reveal that reason as she has heard of the recent news of Scott. What will happen when she is introduced and forced to help out Derek Hale, will he change her? Will she change him? And will he trust what she is?
