Colette Iselin is thrilled to be in Paris for the first time, on a class trip. But a series of gruesome murders are taking place around the city. Colette keeps seeing a strange vision: a pale woman who looks like Marie Antoinette. Colette seeks out the help of a charming French boy and together, they discover that the murder victims are all descendants of people who brought about Marie Antoinettes beheading. And Colette may just be one of those descendants ... which means she might not make it out of this trip alive.
