Linked by Imogen HowsonRead about another book on the list.
15-year-old Elissa has been haunted for years by pain and fear; emotions that don't seem to have anything to do with her or her otherwise untroubled life. This futuristic thriller is set in a world where twins don't exist, at least not legally, and when Elissa discovers that she was born a twin she sets out to find her sibling only to discover that her sister, or "spare" as the authorities have labelled her, has been living a very different existence. Can Elissa save her, against all the odds, or is her twin so damaged she is beyond help? Dubbed as The Bourne Identity meets Inception this YA thriller will appeal to older readers and fans of the Hunger Games and will be available in August [June in the US].
