The future of everyone in the world. Ella Sherfurd has dedicated her life to harnessing a unique gift, the ability to insert herself into people's dreams and memories, using a technique developed by her mother to help others relive their happy memories. But all this is not what it seems. Ella begins to see impossible things: visions of her dead father, warnings of someone she can't trust. Her government recruits her to spy on a group of rebels, using her ability, and influence, in the memories of the traitors. But the rebel leader claims they are in love, even though Ella has never seen him before. Who can say such a thing... Someone has altered her memory. Ella's gift is enough to overthrow a corrupt government or crush a growing group of rebels. She is the key to ending a war she didn't even know about. But if there was someone else inside Ella's head, she can't trust her own memories, thoughts or feelings. So who can she trust?
