Eliza Swan has woken from a year-long coma. Upon waking up, she finds that the perfect life that she had been living was all in fact a dream. She now has to face reality. Her dream world in which her parents were still in love, her brother was still her best friend and her life was perfect doesn't exist. The hardest thing for her to accept, of course, is that her first love, Caleb Wright, the sweet affectionate boy who swept her off her feet was never even real. Depressed and alone, Eliza has to face attending a new school in which she meets a boy named Sebastian Tomms who happens to look identical to Caleb.
Too bad he is the polar opposite of Caleb in every other way - a womanizing inconsiderate guy who takes pleasure in making Eliza's life as difficult as possible.
