DON'T TELL TEACHER

For Lizzie Riley, switching her eight-year-old son Tom to the local academy school marks a fresh start, post-divorce. With its excellent reputation and outstanding results, Lizzie knows it'll be a safe space away from home.

Why is Tom coming home exhausted, unable to remember anything about his day? What are the strange marks on his arm? And when Lizzie tries to question the other children, why do they seem afraid to talk?
