The Lost Twin (Book One)

Book Synopsis
"A creepy boarding school. A sudden disappearance. A secret diary waiting to be found.""This is the story of how I became my sister..."When troublemaker Scarlet goes missing from Rookwood School, her twin sister, Ivy, is invited to 'take her place' - in more ways than one. It's not long before Ivy discovers that secrets are rife and the truth has been concealed.

Ivy is determined to solve the mystery of her sister's disappearance, even if that means going up against the terrifying Miss Fox. Even if that means pretending to be Scarlet for as long as it takes...

Starting Rookwood School
On the first of September 1935, Ivy Grey is surprised when her aunt Phoebe (her father's absent-minded sister) receives a letter from Rookwood School, where Scarlet died several months earlier. When Ivy reads it (because her aunt would forget if she didn't), she finds that she has a place at Rookwood because of Scarlet's death, which is referred to as 'unfortunate circumstances'. Ivy is understandably shocked by that, if not angered by the phrasing.

She's also confused - she failed the original entrance exam for Rookwood, why do they want her? The twin who wasn't good enough? Why isn't the place going to somebody else?

Ivy learns from the deputy headmistress Miss Fox the following day that she will be literally taking Scarlet's place - being mirror twins, she is almost identical to Scarlet but for two things. Ivy is left-handed while Scarlet is right-handed, and their birthmarks are on opposite sides.

In dorm 13, Scarlet's old dorm, Ivy meets Ariadne Flitworth, and they become friends. She also meets Nadia Sayani and Penny Winchester, who are not so friendly, though Ivy doesn't know why. It's something to do with Scarlet though, she's aware of that.
