The Undoing of Violet Claybourne

1938. Gillian Larking is used to blending in and going unnoticed, until she is befriended by her new roommate at boarding school, the vibrant and spirited Violet Claybourne.

As the Christmas holidays approach, Gilly can't believe her luck when Violet invites her to spend them at her home, the crumbling Thornleigh Hall. At Thornleigh, Gilly is dazzled by the family's faded grandeur, and above all by Violet's beguiling older sisters who seem to accept her as one of their own. But following a terrible incident in the house's grounds, Gilly begins to realise the Claybourne sisters aren't quite what she thought they were.

And if she's to survive in their world, she may have to become just like them . . .
