“Mrs. Cass, we were hoping your son could answer a few questions about the girl who disappeared last night…”

Erika Cass has a perfect family and a perfect life. Until the evening when two detectives show up at her front door.

A high school girl has vanished from Erika’s quiet suburban neighborhood. The police suspect the worst–murder. And Erika’s teenage son, Liam, was the last person to see the girl alive.

Erika has always sensed something dark and disturbed in her seemingly perfect older child. She wants to believe he’s innocent, but as the evidence mounts, she can’t deny the truth–Liam may have done the unthinkable.

Now she must ask herself:

How far will she go to protect her son?
