Aidan Jones was my brother. But I couldn't really remember his face. I couldn't remember talking to him or playing with him. He was just a gap, an absence, a missing person.

Before she was adopted by a loving family and raised in a leafy Home Counties town, Cass Montgomery was Cass Jones. Her memories of her birth family disappeared with her name. But when her adopted family starts to break down, a way out comes in the form of a message from her lost brother, Aidan. Having Aidan back in her life is both everything she needs and nothing she expected. Who is this boy who calls himself her brother? And why is he so haunted?

I glance at the paper. There's a big picture on the front page. A girl with dark red hair. A girl with eyes that might have been green or they might have been grey. I sit down and stare at Cass, and it is her, it is. My stolen sister.

Aidan's a survivor. He's survived an abusive stepfather and an uncaring mother. He's survived crowded foster homes and empty bedsits.He's survived to find Cass. If only he can make her understand what it means to be part of his family. . .
