Are you safe in your own home? When Jessica's husband is arrested for fraud, her family's future is thrown into jeopardy. Then the first letter arrives... At first it seems like a sick joke - someone called The Witness claims to be watching Jessica and her children through the windows of their home. But as more letters and disturbing events follow, it's clear that The Witness is real and means to do the family harm. Yet is everything as it seems? Rookie private investigator Emily Swanson is hired to find out the truth. It's the kind of case that could kick-start her career, but as Emily investigates the credibility of the vulnerable family, she soon finds her loyalty called into question--and her life in grave danger. A chilling plan is in motion, and if Emily doesn't uncover who The Witness really is, Jessica and her family will pay a horrifying price.
