A sweet, mysterious teen romance with a refreshing fantasy twist.
California teen Sadie James thinks her life couldn't get any better. She has great friends, an energetic mother she adores, and the beach practically in her own backyard. But her carefree life is turned upside down when she's rescued by a mysterious and strangely familiar boy who won't even tell her his name. Each time the boy appears, Sadie's unexplainable attraction to him deepens along with her need to unravel his secrets. The boy is there to protect her, but as wonderful and exciting as it might be to have an irresistible boy with crystal green eyes protecting her every move, every minute of the day...why does Sadie need one? As Sadie finds answers, she realizes her life isn't as perfect as she thought. Not only is she caught in a world of dangerous secret agents she never knew existed, but it turns out her true identity may be the greatest secret of all.
