Sixteen-year-old Cassandra Renfield has always seen the mark-a light glow reminiscent of candlelight. The only time she pointed it out taught her she shouldn't do it again. For years, the mark has followed Cassie, its rare appearances odd, but insignificant. Until the day she watches a man die. As she revisits each occurrence of the mark, Cassie realizes she can see a person's imminent death. Not how or where, only when: today.
