One of her top ten teen thrillers, as told to the Guardian:
Sister by Rosamund LuptonRead about another book on the list.
A sibling relationship is at the heart of this dark, psychological thriller in which older sister Beatrice searches for her missing younger sister. As the story progresses, Beatrice - shocked by what she finds out about Tess's life - refuses to accept that her sister is gone. This is really powerful storytelling with an amazing twist at the end that I didn't see coming.
