Ivy lives with her slightly crazy aunt while her twin, Scarlet, is at Rookwood School. On her thirteenth birthday, Ivy receives a letter from the school inviting her to join. Ivy dreads going – this is where Scarlet died. Ivy soon realises Miss Fox, the deputy head, is very sinister and soon she forces Ivy to take Scarlet's place, becoming her twin.
So Ivy now has to take on a great challenge. Scarlet and Ivy are like day and night, like chalk and cheese. But she has to remember all her memories of Scarlet otherwise she'll be in trouble. One day, she discovers a diary, Scarlet's, which tells her, bit by bit, the mysteries Ivy desperately wants to solve. Why did Scarlet die? Why did she obey Miss Fox?
After telling her new friend Ariadne and kind ballet teacher Miss Finch the truth, Ariadne and Ivy set off to crack the riddles by Scarlet which should lead them to all the answers. But time is running out. Penny, the school bully, starts to get a little suspicious…
I loved this book as it is a true page-turning, nail-biting mystery. The author has very cleverly hidden clues in the story and let us to solve the mystery as well. I read it in less than a day. It is gripping and keeps you begging for more. I would recommend it to ages 9+.
