'Sharp, original, wickedly astute' Ashley Audrain, Sunday Times bestselling author of The Push

A young teacher is found murdered in the preschool stationery cupboard and the only witnesses are ten toddlers. The problem is the children can't tell the police what happened.

But it soon comes to light that an unsettling medical condition is going around Little Academy: the kids are craving blood, and the parents have been keeping secrets from the authorities that could change everything about the case.

As the police draw closer to the truth, it soon becomes clear that the children are not just witnesses, they're suspects…and so are their mothers.
