Seen a Ghost (5SOS FanFic)

Abigail Richards was a simple 17 year old. There wasn't really anything abnormal about her other than the fact she'd lived in an orphanage all of her life. But when the Garder family takes her in, things start to get a little weird. Why does the air randomly get colder when she's left alone? What's up with the light flickering when no one else is around? And more importantly, why is this all happening to HER?
