Cassandra Renfield has always seen the mark—a glow around certain people reminiscent of candlelight. But the one time she mentioned it, it was dismissed as a trick of the light. Until the day she watches a man awash in the mark die. After searching her memories, Cassie realizes she can see a person’s imminent death. Not how or where, only when: today.

Armed with a vague understanding of the light, Cassie begins to explore her “gift,” seeking those marked for death and probing the line between decision and destiny. Though she’s careful to hide her secret—even from her new philosophy-obsessed boyfriend—with each impending death comes the temptation to test fate. But so many questions remain. How does the mark work? Why is she the only one who sees it? And finally, the most important of all: If you know today is someone’s last, should you tell them? (Summary from Goodreads)
