Centuries of tradition are coming to an end at St Cordula's school. Deputy Head, Fiona Fox, is about to preside over a controversial move to save it from ruin. But it’s not easy to change things at a school this old.

Legend has it that the ghost of fifteenth-century nun, Sister Matilda, will keep St Cordula’s safe. But only as long as the words ‘GOD FORGIVE ME’, scrawled by Matilda on a chapel staircase wall before she fell to her death, are repainted every year. The words have only been allowed to fade once, in 2002. But then, fits of vertigo spread through the pupils, and a second girl fell to her death on the night stairs. Only three people know the truth of what happened on the night of the tragedy.

Now the vertigo is back, and Fiona must stem the outbreak before it threatens St Cordula’s future, or worse, another girl loses her life. But when one of her pupils begins a dangerous investigation into the past, old secrets start to twist into new scandals…
