Zac Silver can’t stop cutting hair. Even with his classmates ordered to wear swimming caps and every pair of scissors locked away – Zac still manages to give Stacy Tatlock a magnificent diagonal-fringed bob during maths. Strict head teacher, Mr Barker, has had enough. Zac Silver's disobedience is not only threatening to ruin Pythagoras Primary's reputation - it's standing in the way of Mr Barker finally affording his dream desk. Somebody’s dream is about to crash and burn. But whose will it be? Illustrations included. Good for 9 to 11 year olds.
