Sara Richardson plans to settle in for a summer full of magical adventures. Trips to Tahiti, vacations in Greece; the world is a playground that Sara can access in the snap of a finger. When Christopher Patrick, Sara's magical partner, tells her that he's moving to Korea with his father, her plans fall apart. She barely has any time to prepare before he's gone in an instant. Replacing him is a pair of mysterious twin girls who seem to possess an air of magic themselves. They move into Chris's house and attempt to befriend Sara. First they try to lure her by mirroring her personality; not an easy task when you're someone as unique as Sara Richardson. When their attempt to win her over fails, they move on to her friends. This only raises more suspicions with Sara; however, she finds that her best friend, Jessica Anderson, may have a motive of her own. Will Sara be able to ward off the evil twins and battle Jessica while her magical partner is half a world away?
