Sorceress — Greg Herren

Laura Pryce, 17, has just completed her junior year of high school when her parents are killed in a car accident and she must go live with her Great Aunt Melisande, whom she has never met. Once at her aunt's huge and rambling house, she discovers a series of paintings. The faces of the women--all from different historical periods--are the same as hers.

Her aunt tells her it's a weird genetic anomaly--that each generation has the face and that it brings with it an exciting future.

But Laura begins to have strange and terrifying dreams. She seeks out friendship in her aunt's assistant--Jake. Jake, however, has secrets of his own. What happened to his family?
As Laura feels increasingly isolated by her surroundings where cell phones fail to work and internet connections easily die, the dreams escalate until Laura cannot discern the difference between what is really a dream and what is happening at the strange, huge house. All she is certain of is that she is in danger...
