Fern communicates with her dog, blisters from just moments in the sun, and has correctly predicted the daily weather for more than two years. Even so, she's always seemed to be a normal twelve-year-old girl . . . until one day when Fern closes her eyes in class and opens them seconds later on a sandy beach miles away from school. When Fern disappears again, this time to a place far more dangerous, she begins to realize exactly how different she is.

With the help of her twin brother, Sam, Fern struggles to gain control of her supernatural powers. The arrival of a sinister vampire in town—who seems to have an alarming interest in Fern's powers—causes Fern to question her true identity. Who is she? More importantly, who can she count on? Soon Fern finds herself in the middle of a centuries-old battle—one that could destroy Fern and endanger everyone she loves.
