When a dangerous situation forces 18-year-old Maria to leave her Boston home, she's swept away to Scotland as part of the Witness Protection Program. ?In a strange land with a new name, Maria hides out as an au pair at the mysterious Harley Estate. Already known as an "over-feeler"-and paranoid for good reason-Maria is spooked by the odd behavior of the Harley residents: from the eccentric kids in her care, to the miserly nurse with the sheet-white skin, to the attractive yet broody eldest son, Jonathan. As the days pass, the vanishing portraits, the cloaked figures and the disembodied humming in the dead of night could perhaps be explained away, but it's the discovery of Harley's macabre and deadly family history that confirms Maria's growing fears and suspicions may be more than just nerves; she may have fallen into something even more horrifying and threatening than what she left behind-something not even of this world.
