Supernatural Love (A Niall Horan Fanfic)

Is it possible to fall in love with someone who is no longer living?
Mariana and her family move to a house that seems to be like any other...except it holds a terrible secret. A boy died in that home several years ago and when Mariana meets that boy, she is determined to find out the secret to his death.
Can she push her love for Niall aside long enough to help him escape the clutches of two demonic forces?
