Alicia Watts has never feared things that go bump in the night. She knows actual terror, and it has nothing to do with the bogeyman. If it weren’t for her sister, Bailey, Alicia would have been the victim of the “monster” known as the system. So when Bailey ends up in a mental institution after being found delusional and roaming the streets, Alicia doesn’t hesitate to rush to her side.

The doctor doesn’t sugarcoat it. Bailey has suffered a severe mental breakdown. She’ll talk to no one, but she’s far from mute. Every waking moment is spent singing the children’s lullaby Hush, Little Baby. Not even their horrid past explains Bailey’s extreme psychosis.

As Alicia searches for answers, she experiences strange events in Bailey’s home… events that make her question everything. What happened to Bailey? Was her sister living a double life? And the one that toys with her head the most … maybe there are things that go bump in the night?
