Your home is the place where you're supposed to feel safe, but what happens when your home is no longer your own?  Uninvited guests have been found living in the homes of people for years without them realizing. Sometimes they are there for shelter and food, but other times their purpose is far more sinister.

Alan Walters, a home inspector, lost everything when an intruder moved into his home without his knowledge and wrecked havoc from hiding places in the walls and attic. Now, three years later, it's happening again to a single mom and her two young children. Follow Alan as he investigates a conspiracy twenty years in the making and comes face-to-face with an evil that has infested this home.

As a grand scheme begins to unfold, Alan uncovers the truth behind this haunted house.  It comes with the cryptic history of an unspeakable horror.  But if these walls could talk, they would be screaming.
