Something evil has swept into the small Maine town of Castle Rock on the heels of the latest winter storm. Sheriff Norris Ridgewick and his team are desperately searching for two missing girls, but time is running out.

In Washington, DC, thirty-seven-year-old Gwendy Peterson couldn’t be more different from the self-conscious teenaged girl who once spent a summer running up Castle Rock’s Suicide Stairs. That same summer, she had been entrusted—or some might say cursed—with the extraordinary button box by Richard Farris, the mysterious stranger in the black suit. The seductive and powerful box offered Gwendy small gifts in exchange for its care and feeding until Farris eventually returned, promising the young girl she’d never see the box again.

One day, though, the button box suddenly reappears but this time, without Richard Farris to explain why, or what she’s supposed to do with it. Between this and the troubling disappearances back in Castle Rock, Gwendy decides to return home. She just might be able to help rescue the missing girls and stop a dangerous madman before he does something ghastly.
