Within the grim walls of Fallbridge College for Girls is Elizabeth Sayers, a new student who, under an assumed name, hopes to learn the truth behind her younger sister's apparent suicide. Our heroine soon learns that the school is in the clutches of a coven of witches called 'The Five' — and that she herself has the right satanic qualities to enable The Five to take over the world!
