This is the story of how I became my sister

A spine-tingling mystery set in a creepily atmospheric boarding school. Ivy
must uncover the secrets behind her twin sister Scarlets disappearance before
its too late.

When troublesome Scarlet mysteriously disappears from Rookwood School,
terrifying Miss Fox invites her quiet twin sister Ivy to take her place.

Ivy reluctantly agrees in the hopes of finding out what happened to her
missing sister. For only at Rookwood will Ivy be able to unlock the secrets of
Scarlets disappearance, through a scattered trail of diary pages carefully
hidden all over the school.

Can Ivy solve the mystery before Miss Fox suspects? Or before an even greater
danger presents itself?

The first in a mesmerising new series perfect for fans of Holly Webb and
Harry Potter and mysteries that demand to be solved!
