Rose Noble lives an ordinary life in the town of Stalworth. Or, at least, as ordinary as can be lived by a girl who became a best-selling writer just out of high school. However, things change when the men in the black coats arrive in town, and some of her best friends start disappearing. Now, it has fallen to her to find out where the victims of the men in the black coats are being kept, if they are alive at all.
