Three days after a tragic accident in New England, Mara Dyer wakes up in a hospital, with no memory of how she got there. Of how her three friends died. Or how she is still alive. Eight weeks later, Mara is in Miami, and is almost living a normal life. She starts at a new school. She makes new friends. And she meets Noah Shaw. He's arrogant, brilliant, beautiful--and Mara falls for him, despite her friends' warnings and her better instincts. But as they grow closer, things happen that make her think there's more to the accident that killed her friends. More to the nightmares and hallucinations she's been having since they died. And more to Noah than he led her to believe. Then two more people connected to her die. Something is happening to Mara, and the truth is buried in her own mind. If she can uncover it, she might be able to save her family. Her first love. Her future. She can try to be normal. But if she can't, she'll have to become something more.
