Keegan (Kiki) Fears was just a normal girl who lived as normal a life that a fifteen year old girl could live. Except her parents were killed by demons (but she didn't know this) and was then adopted by a Warlock and a Shadowhunter. When she gets attacked by a demon, they realize what she didn't know she was. They help investigate what happened to her parents but soon end up dragging her into their mess.
