Harmony House — Nic Sheff

THE KEY TO THEIR SALVATION?
OR PORTAL TO PURE HORROR?

After Jen's alcoholic mother's death, her father cracked. He dragged Jen to this dilapidated old manor on the shore of New Jersey to "start their new lives" -- but Jen can tell that the place has an unhappy history. She can feel it the same way she can feel her anger flowing out of her, affecting the world in strange ways she can't explain.

But Harmony House is more than just a creepy old estate. It's got a chilling past -- and the more Jen discovers its secrets, the more the house awakens. Visions of a strange boy who lived in the house long ago follow Jen wherever she goes, and her fatheri,s already-fragile sanity disintegrates before her eyes.
As the forces in the house join together to terrorize Jen, she must find a way to escape the past she didn't know was haunting her -- and the mysterious and terrible power she didn't .realize sin had.
