Perfect families have the most to hide... I feel so lucky to live in a gorgeous house with my precious daughter on Riverside Road, surrounded by green hills and well-tended gardens. I'm just across from the Taylors, who were a second family to me when I was growing up. But late at night, I spot someone in the house across the street. Someone who shouldn't be there... Lily Taylor and I are best friends and closer than sisters, but life in our idyllic neighbourhood comes to a shuddering halt when I find Lily's father murdered in his own bed. As I break the news to Lily, I swear to her that I'll do everything I can to help her family. Who could possibly have done this? I tell the police, but while they're trying to find the killer, I start getting threatening notes that leave me shaking with fear. Then someone throws a brick through my eleven-year-old daughter Cassie's bedroom window, covering her in shards of broken glass. As I stand in her wrecked bedroom, I make a choice. I am desperate to help Lily get justice, but my daughter's safety has to come first. Even when I stop helping with the investigation, the messages keep coming. Someone knows what I saw, and I'm terrified they'll come for my little girl next. But they've underestimated me. No matter how far I have to go, I'll always protect the people I love... An astonishingly gripping psychological thriller with a truly shocking twist from USA Today bestseller Jill Childs!
